  • Multiple readers on FIFO

    - by poly
    I've asked a question here before about multiple writers on a FIFO, and I know now that the write is thread safe as long as I write less than the PIPE_BIF, here is the link for that limit. What about read? what if have two(or more) readers in multiple threads for reading from the same fifo, do I need locks here? or all I need is to read less than the PIPE_BUF? BTW, I'm talking about Linux FIFO, And I'm using C.

  • More than 5 custom variables across multiple websites using Google Analytics

    - by brakes
    We have multiple websites using the same Google Analytics account number so we can track visitors across multiple websites. One of these websites has set 5 custom variables. We want to introduce a new custom variable to track logged in users for our single sign-on (SSO) system to find out what parts of which website they are accessing. Is this possible or is it a case that all the custom variables have been used up by 1 of the sites?

  • Getting "-bash: fork: Resource temporarily unavailable" in OSX

    - by Joseph Tura
    I seem to run into problems with the max. number of processes every so often. Anyone know what is best practice for fixing this? Running OSX 10.6 on a MacBook Pro i7. ulimit -a returns these values: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited When the error occurred I checked, and there were 102 running tasks and 523 threads.

  • Why are there tons of PHP processes open on my server?

    - by fiftyeight
    Today I saw that a website of mine isn't working so I ssh'd to the server and executed ps -eF. I see about 200 PHP processes that are running all for 4 hours. Apache is built with mpm event and mod fcgid. I killed all the PHP processes and now it's running fine, why does this happen? is this expected behavior? I don't really understand how processes how Apache keeps track of the number of PHP processes and their process IDs, so it would be nice if someone can also give some reference when I can read about this. Also, I used the "ab" command (Apache Benchmark) to see if this happens all the time, so I ran it about 4-5 times with 30 concurrent requests and again there are like 150 PHP processes running, when I keep running "ab" now it doesn't spawn more processes and the website is still working. Please shed some light on this! Thank you :)

  • What happens to running processes when I lose a remote connection to a *nix box?

    - by David Marble
    I occasionally lose my remote SSH connection to my VPS. I use screen for long-running processes, but am wondering what happens to the processes I had running aside from those run within a screen session if I lose the connection to the box. When I re-establish a connection to the box, what happened to the bash and sshd processes that were running when I lost the connection? Today I lost connection repeatedly and noticed many more bash and sshd processes than usual. If there are processes hanging around, do I need to kill them? How could I determine which processes were abandoned from my previous session? Thanks for any replies!

  • how to install daemontools (supervise) on centos 5?

    - by solsol
    I'd like to use supervise to monitor httpd, mysqld and hudson processes on Centos 5. When any of these processes go down I'd like to use a tool to automatically restart them. I've read and heard about supervise, but couldn't find a way to install it on centos. Can anyone help me with that? Any other tools are also good, as long as they can be easily installed on centos 5 and allow me to automatically restart httpd, mysqld, hudson. Thanks for your help!

  • Exclude a process from being listed in `top`

    - by warren
    Is it possible to exclude some processes from being reported by top? For example, I would like to exclude itself from its listing (ie, I don't want top to show in the process list). I would also like to be able to exclude processes that do not belong to the user running top (except for root). Is this possible? If so, how? If not, is there a similar tool that will do what I want (that does not involve running something like ps frequently).

  • Logging from multiple apps/processes to a single log file

    - by Andrew
    Our app servers (weblogic) all use log4j to log to the same file on a network share. On top of this we have all web apps in a managed server logging errors to a common error.log. I can't imagine this is a good idea but wanted to hear from some pros. I know that each web app has its own classloader, so any thread synchronization only occurs within the app. So what happens when multiple processes start converging on a single log file? Can we expect interspersed log statements? Performance problems? What about multiple web apps logging to a common log file? The environment is Solaris.

  • How to indicate to user that a command affects a subset of a multiple selection?

    - by Zamboni
    Here is an example that illustrates my question. I have a program that lists 1000 items. I select 10 of 1000 items. The program enables a button indicating that a command is available for my selection. I click the button, and a window appears. I make some change in the window and click OK. The command changes 5 of the 10 items in my multiple selection, and those 5 changed items now reflect a modified state in my list. My question is: How do I indicate to user that the command affects a subset of a multiple selection before clicking OK? Can anyone cite examples of existing products that handle this scenario well?

  • jquery - how is multiple selection working in this example?

    - by hatorade
    The relevant snippet of HTML: <span class="a"> <div class="fieldname">Question 1</div> <input type="text" value="" name="q1" /> </span> The relevant jQuery: $.each($('.a'), function(){ $thisField = $('.fieldname', $(this)); }); What exactly is being set to $thisField? If my understanding of multiple selectors in jQuery is correct, it should be grabbing the outer <span> element AND the inner <div> element. But for some reason, if I use $thisField.prepend("hi"); it ends up putting hi right before the text Question 1, but not before <div>. I thought multiple selectors would grab both elements, and that prepend() adds hi to the beginning of BOTH elements, not just the <div>

  • Keep it Professional &ndash; Multiple Environments

    - by AjarnMark
    I have certainly been reading blogs a whole lot more than writing them the last several weeks, and it’s about time I got back to writing.  I have been collecting several topics and references for blog posts…some of which will probably just never get written as the timeliness of the topics fade over time.  Nonetheless, I’m back, and I think it is time to revive my Doing Business Right series, this time coming from the slant of managing a development team rather than the previous angle of being self-employed.  First up: separating Dev, Test, and Prod. A few months ago, Colin Stasiuk (@BenchmarkIT) wrote a great post about separating your Dev, Test/UAT, and Prod environments.  This post covers all the important points such as removing Developer access from both PROD and UAT, and the importance of proper deployment (a.k.a. promotion) procedures.  I won’t repeat it all here, go read the original!  But what I do want to address is what I believe to be the #1 excuse people use for not having separate environments:  Money.  I discussed this briefly in my comment on Colin’s post at the time, but let me repeat it here and expand on it a bit. Don’t let the size of your company or the size of its budget dictate whether you do things professionally or not.  I am convinced that most developers and development teams would agree that it is a best practice to have separate environments for development, testing, and production (a.k.a. Live).  So why don’t they?  Because they think that it means separate servers which means more money.  While having separate physical servers for the different environments would be ideal, it is not an absolute requirement in order to make this work.  Here are a few ideas: Use multiple instances of SQL Server and multiple Web Sites with Headers or Ports.  For no additional fees* you can install multiple instances of SQL Server on the same machine.  This gives you a nice separation, allowing you to even use the same database names as will appear in PROD, yet isolating the data and security access.  And in IIS, you can create multiple Web Sites on the same server just by using Host Headers or different port numbers to separate them.  This approach does still pose the risk of non-Prod environments impacting performance on Prod, but when your application is busy enough for that to be a concern, you can probably afford one of the other options. Use desktop PCs instead of servers.  Instead of investing in full server-grade hardware, you can mimic the separate environments on old desktop PCs and at least get functional equivalency, if not performance matching.  The last I checked, Microsoft did not require separate licensing for SQL Server if that installation was used exclusively for dev or test purposes*.  There may be some version or performance differences between this approach and what you have in Prod, but you have isolated test from impacting Prod resources this way. Virtualization.  This is of course one of the hot topics of the day, and I would be remiss if I did not suggest this.  It is quite easy these days to setup virtual machines so that, again, your environments are fairly isolated from one another, and you retain all the security and procedural benefits of having separate environments. So the point is, keep your high professional standards intact.  You don’t need to compromise on using proper procedure just because you work in a small company with a small budget.  Keep doing things the right way! By the way, where I work, our DEV environment is not on a server.  All development is done on the developer’s individual workstation where it can be isolated from other developers’ work for the duration of writing the code, but also where the developers have to reconcile (merge) differences in code under concurrent development.  This usually means that each change is executed multiple times (once per developer to update their environments with the latest changes from others) giving us an extra, informal. test deployment before even going to the Test/UAT server.  It also means that if the network goes down, the developers can continue to hum along because they are not dependent on networked resources.  In fact, they will likely be even more productive because they aren’t being interrupted by email…but that’s another post I need to write. * I am not a lawyer, nor a licensing specialist, but it appeared to be so the last time I checked.  When in doubt, consult an expert on the topic.

  • How to "signal" interested child processes (without signals)?

    - by Teddy
    I'm trying to find a good and simple method to signal child processes (created through SocketServer with ForkingMixIn) from the parent process. While Unix signals could be used, I want to avoid them since only children who are interested should receive the signal, and it would be overkill and complicated to require some kind of registration mechanism to identify to the parent process who is interested. (Please don't suggest threads, as this particular program won't work with threads, and thus has to use forks.)

  • PHP Processes reaching limit along with FastCGI timeouts

    - by Constant M
    I have a problem similar to http://stackoverflow.com/questions/1168384/how-to-troubleshoot-php-processes, but with a twist. We have a couple of managed servers that recently migrated to FastCGI. Since then we've been having problems. We have a content management system at a central place that we manage all our sites with. All the sites run on the same managed server. So basically its one PHP script that generates pages on the same server. The catch comes in where it works perfectly on some, and gives FCGI timeout errors on others. At the same time our support is saying that the PHP processes heap up to their limit and then causes Apache to stop working. I'm convinced this is a fault on their side, but would like to get my side clean too. Anyway have any suggestions where I can start looking for what's going wrong? I know it's a really broad question, but any help or pointers would be great. Thanks Just to add to that, here's a PS printout from support: happyh 13853 21556 0 01:04 ? 00:00:00 /usr/bin/php5-cgi happyh 13869 13853 0 01:04 ? 00:00:00 /usr/bin/php5-cgi mamedc 13914 21556 0 05:14 ? 00:00:00 /usr/bin/php5-cgi wealthf 13947 21556 0 01:21 ? 00:00:00 /usr/bin/php5-cgi wealthf 13961 13947 0 01:21 ? 00:00:00 /usr/bin/php5-cgi mamedc 14032 13914 0 05:14 ? 00:00:00 /usr/bin/php5-cgi lookgrt 14157 21556 0 04:47 ? 00:00:00 /usr/bin/php5-cgi lookgrt 14178 14157 0 04:47 ? 00:00:00 /usr/bin/php5-cgi wolfie 14262 21556 0 01:08 ? 00:00:00 /usr/bin/php5-cgi wolfie 14276 14262 0 01:08 ? 00:00:00 /usr/bin/php5-cgi yaukrl 14352 21556 0 01:21 ? 00:00:00 /usr/bin/php5-cgi yaukrl 14361 14352 0 01:21 ? 00:00:00 /usr/bin/php5-cgi itpays2 14538 21556 0 01:33 ? 00:00:00 /usr/bin/php5-cgi itpays2 14547 14538 0 01:33 ? 00:00:00 /usr/bin/php5-cgi brichmbx 14732 21556 0 04:47 ? 00:00:00 /usr/bin/php5-cgi brichmbx 14803 14732 0 04:47 ? 00:00:00 /usr/bin/php5-cgi greatl 14969 21556 0 01:00 ? 00:00:00 /usr/bin/php5-cgi

  • How to run several fastcgi processes for nginx (spawn-fcgi)

    - by SPnova
    I want to run several fastcgi processes with different users and different php.ini . But unfortunately I found information about running one process only. http://www.howtoforge.com/installing-nginx-with-php5-and-mysql-support-on-ubuntu-9.04 There is mod suexec for Apache which allows to do it. Does anyone know something like that for fastcgi php nginx?
