• PHP MYSQL Insert Data in Arabic Language

  - by h_a86

  I am trying to insert some Arabic Language data into MySQL using PHP and an HTML form. When I insert the data in to MYSQL table, the table field represents data as مرحبا العالم. But when I access the same data with PHP and show it in my webpage, it shows the correct data. I am using: http-equiv="Content-Type" content="text/html; charset=utf-8" meta tag in my web page to show Arabic data. My question is why my data looks like this: مرحبا العالم in MySQL table, and how should I correct it.

• NoMethodError in UsersController#create

  - by Mike DeVerna

  I'm getting stuck on an error I'm getting when signing up a new user in Michael Hart's Ruby on Rails Tutorial. I'm new to rails but I've been searching for hours and can't seem to find anything to figure out the issue. My initial thought is that it's specific to the following line: redirect_to @user This is my file for users_controller.rb #!/bin/env ruby # encoding: utf-8 class UsersController < ApplicationController def show @user = User.find(params[:id]) end def new @user = User.new end def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome to the Sample App!" ?????????????? redirect_to @user else render 'new' end end end This is the error message I get: NoMethodError in UsersController#create undefined method `??????????????' for # Rails.root: /Users/mikedeverna/Documents/rails_projects/sample_app Application Trace | Framework Trace | Full Trace app/controllers/users_controller.rb:18:in `create' Here is the code in my routes.rb file: SampleApp::Application.routes.draw do resources :users resources :sessions, only: [:new, :create, :destroy] root to: 'static_pages#home' match '/signup', to: 'users#new' match '/signin', to: 'sessions#new' match '/signout', to: 'sessions#destroy', via: :delete match '/help', to: 'static_pages#help' match '/about', to: 'static_pages#about' match '/contact', to: 'static_pages#contact'

  I have a button named searchReportButton. On this button click, I need to check session value from server using a ajax web method "Error.aspx/CheckSessionExpiry".This is done in checkSession javascript function.

  I'm having a trouble that I can't export japanese texts to excel (xls). I used the following codes: header('Content-type: application/ms-excel;charset=UTF-8'); header('Content-Disposition: attachment; filename='.$filename); header("Pragma: no-cache"); echo $contents; But in the excel file, the text changed to funny characters like this: é™?定ç‰? ã?¨ã??ã?¯ã??ã?£ã?†ã?ªã?¢å??犬ã?®ã?Œæ??ã? ’è??ã??ã?Ÿã?†ã?£ã??ã??ã??ã?? ï??

• how to generate XML (in String representation) in java

  - by flyingfromchina

  I have defined a java class, but only need to output some of the fields of this class into an XML. The returned type must be a String. I first opted for the easiest way using a StringBuffer. However, when I tried to process the output String represenation, it failed. I think it is mostly likely because there are some characters that are not encoded in the UTF-8 in the input. Could someone tell me what is the best way to handle this? Thanks.

• prettyPhoto not working in my wordpress theme

  - by codemanic

  So friends I am trying to use prettyPhoto in my wordpress theme but its not working at all. Both of its files - prettyPhoto.css and jquery.prettyPhoto.js are correctly linked in header.php file. This is the linking of the files in my header.php file - <link rel="stylesheet" href="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/css/prettyPhoto.css" type="text/css" media="screen" title="prettyPhoto main stylesheet" charset="utf-8" /> <script src="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/js/jquery.prettyPhoto.js" type="text/javascript"></script> Please let me know if this problem is due to not using wp_enqueue_script(). And this is how I link the image to be used with prettyPhoto - <a title="test image" href="images/new-image.png" rel="prettyPhoto[]"><img src="images/new-image.png" alt="Some Alternate Text" /></a> When I click on image, it doesn't open in prettyPhoto.

• Accessing ajax POST response in javascript

  - by mike44

  I'm making ajax POST request from javascript function: function UpdateMetrics() { $.ajax({ type: "POST", url: "MyHandler.ashx?Param1=value1", data: "{}", contentType: "text/json; charset=utf-8", dataType: "text", success: function (msg) { var jsonUpdatedData = msg; ... } }); } From my handler, I'm sending json string with: context.Response.write(json); I think I'll get it in msg. I also want to send other string (count). So I'm trying to use header info along with json data. So I added this line: context.Response.Headers.Add("MaxCount",Convert.ToString(tempList.Count)); If this is right way to do it, how can I access it in my success function?

• mysqldb python escaping ? or %s?

  - by asldkncvas

  Dear Everyone, I am currently using mysqldb. What is the correct way to escape strings in mysqldb arguments? Note that E = lambda x: x.encode('utf-8') 1) so my connection is set with charset='utf8'. These are the errors I am getting for these arguments: w1, w2 = u'??', u'??' 1) self.cur.execute("SELECT dist FROM distance WHERE w1=? AND w2=?", (E(w1), E(w2))) ret = self.cur.execute("SELECT dist FROM distance WHERE w1=? AND w2=?", (E(w1), E(w2)) ) File "build/bdist.linux-i686/egg/MySQLdb/cursors.py", line 158, in execute TypeError: not all arguments converted during string formatting 2) self.cur.execute("SELECT dist FROM distance WHERE w1=%s AND w2=%s", (E(w1), E(w2))) This works fine, but when w1 or w2 has \ inside, then the escaping obviously failed. I personally know that %s is not a good method to pass in arguemnts due to injection attacks etc.

• Optimizing apache server load

  - by Jevgeni Smirnov

  We have an issue with a dedicated server load. We have 16 processors with 4 core @ 2.40GHz, if I understood correctly cat /proc/cpuinfo output. Unfortunately, I don't have access to free -m or vmstat. But from top I got that we have 24 GB. And snapshot from top about processes: As far as I see, memory is not used at all. But the cpu is used heavily. Apache consumes most of CPU.

• Cannot Start Nginx Compiled from Source

  - by Jason Alan Kennedy

  I am trying to compile Nginx from source based on the original compiled Nginx server running on my DigitalOcean server ( Ubuntu-14.04 64x ) but with a few extra modules. I can get everything installed smoothly but I can not get it to start. I am sure the ini is correct because I copied the original source off the current running Nginx server [ Even though I see that Nginx now adds the ini when compiling fron source ]. Below is the [ lengthy process ] that I am performing - add sorry but I wanted to be thorough for those who are in need of the info ]. Because I am a newB to Nginx, I am sure I am missing something or just have it all wrong. If you may look over what I have done and see if you spot anything I need/need to change, I will greatly appreciate it. Thnx!

If you need to see the conf files I copied over from the old to the custom server, LMK and I'll post them. Again your help here would be appreciated!

• Need help trouble shooting high CPU usage by PHP-fpm

  - by user432506

  There is a problem that is driving me crazy. After the day I tried to fix the CPU usage problem of my VPS, the CPU load has grown from 60% to 150%, and I have no idea what causes the problem. Please help me. I had installed a copy of mediawiki on a Linode 1024. The wiki is running on Niginx + PHP-fpm + MySql. The wiki doesn't have much traffic, only around 4000 requests/day, mostly from Google and Bing bots. It had been using around 60% (of total 400% on the Linode) of the CPU before. I thought it was a bit high, so two day ago, I was trying to fix the problem (not knowing what was waiting for me). I did nothing but added a new empty line to wiki's configure file, which would change the modified time of the configure file, and then all the cached page files would be set invalidated. I had done that before, and that would cause high CPU usage, but normally it would take only hours to let things back to normal again. Not this time, my CPU usage has been around 150% for more than two days. It is php-fpm using most of CPU reassures. Using 100% of three cores is not rare. I hadn't seen that before. There are other sites on the Linode, but it should be the wiki. Because if I offline the wiki, CPU usage will drop back to around 40% soon. The day I also duplicated php-fpm.conf, and opened it, but didn't changed it. I have no idea what I did wrong. I here ask for help to save myself from being crazy!!! It is php-fpm. Is there a way to find out what is it doing?

• Using AuthzSVNAccessFile for controlling SVN Access produces HTTP 400 Bad Request

  - by meeper

  I have a new repository on an existing subversion server that requires us to perform path based authorization within the repository. I found that the AuthzSVNAccessFile directive in apache is directly responsible for allowing this functionality. After fixing several other problems such as AuthzSVNAccessFile preventing SVNListParentPath from operating properly, I am left with one single problem. I can checkout, I can update, I can commit, BUT I cannot execute an SVN COPY for performing branch/tagging operations. The moment I comment out the AuthzSVNAccessFile line in the Apache config everything works as expected except the obvious path authorizations. Versions: The server OS is Debian 6.0.7 (Squeeze) Apache 2.2.16-6+squeeze11 Server Subversion 1.6.12dfsg-7 Clients are running windows Clients tried are: TortoiseSVN 1.8.2 Build 24708 64bit SVN CLI Client 1.8.3 (r1516576) Authentication is performed via AD to a Windows 2003 domain and appears to be operating normally. I have stripped out all other configurations and repository setups to produce this single configuration that reproduces the problem. Apache Configuration: <VirtualHost *:443> ServerName svn-test.company.com ServerAlias /svn-test ServerAdmin [email protected] SSLEngine On SSLCertificateFile /etc/apache2/apache.pem ErrorLog /var/log/apache2/svn-test_error.log LogLevel warn CustomLog /var/log/apache2/svn-test_access.log combined ServerSignature On # Repository Access to all Repositories <Location "/"> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthBasicProvider ldap AuthType Basic AuthzLDAPAuthoritative Off AuthName "Subversion Test Repository System" AuthLDAPURL "ldap://adserver.company.com:389/DC=corp,DC=company,DC=com?sAMAccountName?sub?(objectClass=*)" NONE AuthLDAPBindDN "CN=service_account,OU=ServiceIDs,OU=corp,OU=Delegated,DC=na,DC=corp,DC=company,DC=com" AuthLDAPBindPassword service_account_password Require valid-user SSLRequireSSL </Location> # <LocationMatch /.+> is a really dirty trick to make listing of repositories work # http://d.hatena.ne.jp/shimonoakio/20080130/1201686016 <LocationMatch /.+> AuthzSVNAccessFile /etc/apache2/svn_path_auth </LocationMatch> </VirtualHost> SVN Access File: [/] * = rw The repository used (AuthTestBasic) consists of the following directory structure and contains no externals (this is a literal listing, not an example): / /branches/ /tags/ /trunk/ /trunk/somefile.txt Tortoise produces the following error during a tag operation in it's tag result window: Adding directory failed: COPY on /authtestbasic/!svn/bc/2/trunk (400 Bad Request) The svn.exe CLI client produces the following error: C:\Users\e20epkt>svn copy https://servername/authtestbasic/trunk https://servername/authtestbasic/tags/tag1 -m "svn cli client" svn: E175002: Adding directory failed: COPY on /authtestbasic/!svn/bc/2/trunk (400 Bad Request) The Apache error log has nothing in it, however the apache access log has the following in it (IP addresses and usernames changed obviously): 10.1.2.100 -

I have also confirmed that all files for the repository (/var/svn/authtestbasic) are owned by the Apache user www-data.

• Apache2 mod_proxy to remote Tomcat7 - slow response

  - by 12N

  Been stuck with this one for a few days. Will try to provide as much information as possible, but please feel free to ask for extra detail. I have 2 VMs behind a NAT, 192.168.0.100 and 192.168.0.102, both running Ubuntu 11.04 x64. The first one is mapped to the exterior and is our webserver, has one Apache/2.2.17 install with several vhosts to serve static content, and there's also mod_jk for load balancing. The second one has a tomcat 7 install with several J2EE REST webservices but no apache - requests are expected to be passed directly from .100 apache to .102 tomcat. It is my intention to prepare a tomcat clustered environment. My problem: Requests reach to 192.168.0.100 with no trouble whatsoever, but then take about... 100 seconds for data to actually arrive to .102 - by that time apache has already timeouted, but tomcat receives and processes the request pretty normally. This happens both when using mod_jk, mod_proxy, or mod_ajp_proxy. No idea why, since there are no firewalls in either of the machines, both are pingable - more than that, there are NFS shares active working like a charm - and a mod_proxy experience shown that requests originating directly from .100 are processed normally. Also, to add insult to injury, a similar environment is set up at our office network. Everything works perfectly. -_- The only difference? We have no ip translation at the office and do everything by internal addresses - dunno if that's relevant in any way. Some configs: Apache vhost: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/ ServerName www.example.com ProxyRequests Off <Proxy *> Options Indexes FollowSymLinks MultiViews AllowOverride all Order allow,deny allow from all </Proxy> ProxyPass /bork http://192.168.0.102:8080/bork ProxyPassReverse /bork http://192.168.0.102:8080/bork LogLevel debug CustomLog ${APACHE_LOG_DIR}/api_access.log combined ErrorLog ${APACHE_LOG_DIR}/api_error.log </VirtualHost> Tomcat connectors <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" /> And a debug log from apache, from a test using mod_proxy_ajp. The behavior is pretty much the same in mod_proxy, at least regarding the delay. Please note that tomcat eventually receives and processes the request, more or less when the log starts being updated again: [Sun May 06 14:40:33 2012] [debug] proxy_util.c(1506): [client

• Why does my MacBook Pro have long ping times over Wi-Fi?

  - by randynov

  I have been having problems connecting with my Wi-Fi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10 seconds before slowly coming back down. You can see the trend below. I'm on a MacBook Pro and have done the normal stuff (reset the PRAM and SMC, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 and 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation?

• What does it mean when ARP shows <incomplete> on eth1

  - by Geoff Dalgas

  We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing. Are there any additional troubleshooting steps we can take help resolve this issue? THINGS WE HAVE TRIED I added a static arp entry for testing on one of the linux gateways which still didn't help. root@haproxy2:~# arp -a peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-221.peak.org (69.59.196.221) at 00:15:5d:00:b2:0d [ether] on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 peak-colo-196-220.peak.org (69.59.196.220) at 00:21:5e:4d:30:8d [ether] PERM on eth1 root@haproxy2:~# arp -i eth1 -s 69.59.196.220 00:21:5e:4d:30:8d root@haproxy2:~# ping 69.59.196.220 PING 69.59.196.220 (69.59.196.220) 56(84) bytes of data. --- 69.59.196.220 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6006ms Rebooting the windows web server solves this issue temporarily with no other changes to the network but our experience shows this issue will come back. Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps.

• Gearman too many processes issue

  - by Roman Newaza

  I use Net_Gearman from PECL, Gearmand 1.1.11 and Gearman Manager. Every time I add background job, I can see new worker listed with no Function, nor Id in Ggearman-Monitor: If I add many messages in the bash loop, after some time it becomes very slow. for i in $(seq 0 9999); do php Client.php && echo $i; done Yesterday, the situation was even worse - I had many error messages in Gearmand log regarding Too many open files and once I added --file-descriptors=49152 as an option and swithched to 1.1.11 from 1.0.6, these errors gone.

• heimdal kerberos in openldap issue

  - by Brian

  I think I posted this on the wrong 'sister site', so here it is. I'm having a bit of trouble getting Kerberos (Heimdal version) to work nicely with OpenLDAP. The kerberos database is being stored in LDAP itself. The KDC uses SASL EXTERNAL authentication as root to access the container ou. I created the database in LDAP fine using kadmin -l, but it won't let me use kadmin without the -l flag: root@rds0:~# kadmin -l kadmin> list * krbtgt/REALM kadmin/changepw kadmin/admin changepw/kerberos kadmin/hprop WELLKNOWN/ANONYMOUS WELLKNOWN/org.h5l.fast-cookie@WELLKNOWN:ORG.H5L default brian.empson brian.empson/admin host/rds0.example.net ldap/rds0.example.net host/localhost kadmin> exit root@rds0:~# kadmin kadmin> list * brian.empson/admin@REALM's Password: <----- With right password kadmin: kadm5_get_principals: Key table entry not found kadmin> list * brian.empson/admin@REALM's Password: <------ With wrong password kadmin: kadm5_get_principals: Already tried ENC-TS-info, looping kadmin> I can get tickets without a problem: root@rds0:~# klist Credentials cache: FILE:/tmp/krb5cc_0 Principal: brian.empson@REALM Issued Expires Principal Nov 11 14:14:40 2012 Nov 12 00:14:37 2012 krbtgt/REALM@REALM Nov 11 14:40:35 2012 Nov 12 00:14:37 2012 ldap/rds0.example.net@REALM But I can't seem to change my own password without kadmin -l: root@rds0:~# kpasswd brian.empson@REALM's Password: <---- Right password New password: Verify password -

• PHP pages working slow from time to time

  - by user1038179

  I have VPS with limit of 2GB of ram and 8 CPU cores. I have 5 sites on that VPS (one of them is just for testing, no visitors exept me). All 5 sites are image galleries, like wallpaper sites. Last week I noticed problem on one site (main domain, used for name servers, and also with most traffic, visitors). That site has two image galleries, one is old static html gallery made few years ago and another, main, is powered by ZENPhoto CMS. Also I have that same gallery CMS on another two sites on that same VPS (on one running site and on one just for testing site). On other two sites I have diferent PHP driven gallery. Problem is that after some time (it vary from 10 minutes to few hours after apache restart), loading of pages on main site becomes very slow, or I get 503 Service Temporarily Unavailable error. So pages becomes unavailable. But just that part with new CMS gallery, old part of site with static html pages are working fast and just fine. Also other two sites with same CMS gallery and other two with different PHP driven gallery are working fine and fast at the same time. I thought it must be something with CMS on that main site, because other sites are working nice. Then I tryed to open contact and guest book pages on that main site which are outside of that CMS but also PHP pages, and they do not load too, but that same contact php scipts are working on other sites at the same time. So, when site starts to hangs, ONLY PHP generated content is not working, like I said other static pages are working. And, ONLY on that one main site I have problems. Then I need to restart Apache, after restart everything is vorking nice and fast, for some time, than again, just PHP pages on main site are becomming slower. If I do not restart apache that slowness take some time (several minutes, hours, depending ot traffic) and during that time PHP diven content is loading very slow or unavailable on that site. After sime time, on moments everything start to work and is fast again for some time, and again. In hours with more traffic PHP content is loading slowly or it is unavailable, in hours with less traffic it is sometimes fast and sometimes little bit slower than usually. And ones again, only on that main site, and only PHP driven pages, static pages are working fast even in most traffic hours also other sites with even same CMS are working fast. Currently I have about 7000 unique visitors on that site but site worked nice even with 11500 visitors per day. And about 17000 in total visitors on VPS, all sites ( about 3 pages per unique visitor). When site start to slow down sometimes in apache status I can see something like this: mod_fcgid status: Total FastCGI processes: 37 Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 11300 39 28 7 Working 11274 47 28 7 Working 11296 40 29 3 Working 11283 45 30 3 Working 11304 36 31 1 Working 11282 46 32 3 Working 11292 42 33 1 Working 11289 44 34 1 Working 11305 35 35 0 Working 11273 48 36 2 Working 11280 47 39 1 Working 10125 133 40 12 Exiting(communication error) 11294 41 41 1 Exiting(communication error) 11277 47 42 2 Exiting(communication error) 11291 43 43 1 Exiting(communication error) 10187 108 43 10 Exiting(communication error) 10209 95 44 7 Exiting(communication error) 10171 113 44 5 Exiting(communication error) 11275 47 47 1 Exiting(communication error) 10144 125 48 8 Exiting(communication error) 10086 149 48 20 Exiting(communication error) 10212 94 49 5 Exiting(communication error) 10158 118 49 5 Exiting(communication error) 10169 114 50 4 Exiting(communication error) 10105 141 50 16 Exiting(communication error) 10094 146 50 15 Exiting(communication error) 10115 139 51 17 Exiting(communication error) 10213 93 51 9 Exiting(communication error) 10197 103 51 7 Exiting(communication error) Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7983 1079 2 149 Ready 7979 1079 11 151 Ready Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7990 1066 0 57 Ready 8001 1031 64 35 Ready 7999 1032 94 29 Ready 8000 1031 91 36 Ready 8002 1029 34 52 Ready Process: php5 (/usr/local/cpanel/cgi-sys/php5)Pid Active Idle Accesses State 7991 1064 29 115 Ready When it is working nicly there is no lines with "Exiting(communication error)" Active and Idle are time active and time since last request, in seconds.
