  • MySQL is hogging my server resources

    - by Reacen
    Does anyone have any idea of what can cause this weird behaviour and how I go about fixing it? This is all coming from MySQL only (both RAM and CPU usage), for about 10 minutes after I reboot my Java game server (that has a pool of 256 connections). There are not that many queries and I think it may be more of a MySQL misconfiguration problem. My server: 3.20 GHz * 6 core / 24 GB RAM / 64 bit Windows Server 2003. My game server: Java server, with 256 MySQL connections pool (MyISAM engine), about 500,000 accounts, and 9 million rows of game items in database and about 3,000 players are connected. After about 15 minutes of the game server reboot, the server resumes its stability and CPU usage drop down to 1% ~ 5% and memory to 6 GB. Here is a copy of my MySQL configuration. Also, any advice about my MySQL configuration will be appreciated. I really set it up almost at random. # Example MySQL config file for very large systems. # # This is for a large system with memory of 1G-2G where the system runs mainly # MySQL. # # You can copy this file to # /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options (in this # installation this directory is C:\mysql\data) or # ~/.my.cnf to set user-specific options. # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] #log=c:\mysql.log port = 3306 socket = /tmp/mysql.sock skip-locking key_buffer_size = 2572M max_allowed_packet = 64M table_open_cache = 512 sort_buffer_size = 128M read_buffer_size = 128M read_rnd_buffer_size = 128M myisam_sort_buffer_size = 500M thread_cache_size = 32 query_cache_size = 1948M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 12 max_connections = 5000 # Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host. # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows # (via the "enable-named-pipe" option) will render mysqld useless! # #skip-networking # Replication Master Server (default) # binary logging is required for replication log-bin=mysql-bin # required unique id between 1 and 2^32 - 1 # defaults to 1 if master-host is not set # but will not function as a master if omitted server-id = 1 # Replication Slave (comment out master section to use this) # # To configure this host as a replication slave, you can choose between # two methods : # # 1) Use the CHANGE MASTER TO command (fully described in our manual) - # the syntax is: # # CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, # MASTER_USER=<user>, MASTER_PASSWORD=<password> ; # # where you replace <host>, <user>, <password> by quoted strings and # <port> by the master's port number (3306 by default). # # Example: # # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, # MASTER_USER='joe', MASTER_PASSWORD='secret'; # # OR # # 2) Set the variables below. However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # # binary logging format - mixed recommended #binlog_format=mixed # Point the following paths to different dedicated disks #tmpdir = /tmp/ #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = C:\mysql\data/ #innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend #innodb_log_group_home_dir = C:\mysql\data/ # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 384M #innodb_additional_mem_pool_size = 20M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 100M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 64M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 256M sort_buffer_size = 256M read_buffer = 8M write_buffer = 8M [mysqlhotcopy] interactive-timeout

  • Operation not permitted when starting Unicorn

    - by fiskeben
    I've created an nginx/unicorn/capistrato setup on Ubuntu (Amazon EC2) by following mostly this guide. I guess everything is set up like it should but when I start Unicorn I get (a LOT of) this error in the log: E, [2012-09-08T08:57:20.658092 #12356] ERROR -- : Operation not permitted (Errno::EPERM) /home/deployer/apps/bridgekalenderen.no/shared/bundle/ruby/1.9.1/gems/unicorn-4.3.1/lib/unicorn/worker.rb:82:in `initgroups' I see it's related to the user's permissions but I just can't figure out what I've left out. The server starts up nicely if I start it with sudo (or, rvmsudo, really). The user has sudo capabilities, I have chmod'ed the app several times so the file permissions there should be ok. The unicorn socket in /tmp is owned by the deployer user, so that shouldn't be the problem either. Does anybody have a clue where to look?

  • Tomcat 6 HTTPS connector: keep alive timeout not being respected

    - by sehugg
    I'm using Tomcat 6.0.24 on Ubuntu (JDK 1.6) with an app that does Comet-style requests on an HTTPS connector (directly against Tomcat, not using APR). I'd like to set the keep-alive to 5 minutes so I don't have to refresh my long-polling connections. Here is my config: <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="1000" keepAliveTimeout="330000" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" /> Unfortunately it seems that the server closes the connection after 65 seconds. The pcap from a sample session goes something like this: T=0 Client sends SYN to server, handshake etc. T=65 Server sends FIN to client T=307 Client sends FIN to server (I'm guessing the 5 minute timeout on the client is due to the HTTP lib not detecting the socket close on the server end, but in any case -- the server shouldn't be closing the connection that early) (edit: this works as expected when using the standard HTTP connector)

  • Gateway SX2300-01u CPU/PSU issues

    - by Vlad
    I have a 2-yr-old Gateway SX2300-01u with an AMD Phenom X3 8550 that I feel has about a year or so of life left, but I am having a couple of hardware issues that I have not been able to resolve. First, the power supply fan sounds like much louder than before and the PSU itself is really hot. The PSU model (Liteon PS 5221-06) is not available at a reasonable price; are there any good alternatives? Could I replace just the PSU fan? Also, the CPU fan failed sometime back, but my replacement, which supposedly fits the MB (Socket AM2+) doesn't actually fit properly. Any idea why?

Today or tomorrow there will be an app that will do this automatically. How do they make this kinds of applications? Can you give me some idea on what programming language do they use. And how do they do it. Please enlighten me

  • Linux - Only first virtual interface can ping external gateway

Looking at the example config file: cat /usr/share/doc/dovecot-common/dovecot/example-config/dovecot.conf was of no help. Dovecot is running: ps -A | grep 'dovecot' 9663 ? 00:00:00 dovecot But I can't seem to get that elusive "dovecot-auth" process. Anyone know what's going on?

  • How to monitor current output/receive queue length in Linux

    - by IZhen
    I want to check the capacity and performance of my network. Besides checking the txkB/s and rxkB/s via Sar, I'd also like to see the average queue length of the network interface(so that the average queueing time in the interface can be calculated). It seems that netstat can give a per socket queue length, is it possible to get a per interface statics(a bit like Network Interface\Output Queue Length in Windows)? A related and kind of reverse questions is How do I view the TCP Send and Receive Queue sizes on Windows? Thanks

  • Debian Unstable + Postfix 2.6.5 + dkim-filter 2.8.2 issue

    - by kura
    I have Postfix installed on Debian Unstable, as the title states, the system is completely up-to-date, I have tried to get DKIM signatures working on outgoing mail using dkim-filter 2.8.2. I couldn't use the default Debian way of doing things with sockets, instead I used the Ubuntu way: SOCKET="inet:12345@localhost"` I have the following in my postfix/main.cf milter_default_action = accept milter_protocol = 6 smtpd_milters = inet:localhost:12345 non_smtpd_milters = inet:localhost:12345 All is fine except I get the following message I start DKIM in mail.log: dkim-filter[22029]: can't configure DKIM library; continuing And when it tries to sign mails I get the following error: postfix/cleanup[22042]: warning: milter inet:localhost:12345: can't read SMFIC_EOH reply packet header: Success And then dkim-filter daemon stops. I've looked through Google but found no actual way to fix this that works for me. I have this working fine on an Ubuntu server but would love to get it working on Debian too.

  • Delay between printing via lp in opensuse

    - by adamweeks
    I am experiencing a 10-15 second delay when printing multiple documents to a barcode printer in opensuse. I have had the same setup on other systems with older versions of opensuse without any issue. The setup is as follows: The print queue is setup as a "generic with driver Raw Queue". The files being sent down to the printers are simple text files with the lp command: lp -dprinter1 /path/file The printer is a JetDirect compatible device (Intermec brand) with a standard 9100 port socket setup. If I send a multi-page document to the printer, it will print nonstop the multiple pages. If I send 2 or more text files down via separate "lp" commands, the delay will be there between each printout. I've tried multiple different printers and they all experience the same issue.

    - by HardwareMuch
    How do other people tweak or edit Tomato firmware? I'm interested in this because I do not need QoS. I have another router that does not have as much RAM and I want to have a micro Tomato firmware. I know there is DD-WRT micro but I like Tomato much more. What programming language is used in making Tomato firmware?

  • Firefox does not load certificate chain

    - by TimWolla
    I'm running lighttpd/1.4.28 (ssl) on Debian Squeeze. I just created a http://startssl.com certificate, I runs fine at all of my Browsers (Firefox, Chrome, Opera), but my users are reporting certificate-errors in Firefox. I already nailed it down to a failing of loading of the certificate chain: Certificate at my Firefox: http://i.stack.imgur.com/moR5x.png Certificate at others Firefox: http://i.stack.imgur.com/ZVoIu.png (Note the missing StartCOM-certificates here) I followed this tutorial for embedding the certificate in my lighttpd: https://forum.startcom.org/viewtopic.php?t=719 The relevant parts of my lighttpd.conf look like this: $SERVER["socket"] == ":443" { ssl.engine = "enable" ssl.ca-file = "/etc/lighttpd/certs/ca-bundle.pem" ssl.pemfile = "/etc/lighttpd/certs/www.bisaboard.crt" } ca-bundle.pem was created like this: cat ca.pem sub.class1.server.ca.pem > ca-bundle.pem I grabbed the relevant files from here: http://www.startssl.com/certs/ www.bisaboard.crt was created like this: cat certificate.pem ssl.key > www.bisaboard.crt Where certificate.pem is my StartSSL-Class1 Certificate and ssl.key my SSL-Root-Key. Do you have any idea why the second Firefox does not correctly load the certificate-chain?

  • Can I drive two external screens from an 'Alu' iMac?

    - by robsoft
    I've got a 24" 2.4 Ghz Core 2 Duo iMac. It's about 18 months old, though I can't specifically remember when I bought it. It has a Displayport Mini-DVI socket on the back, and currently I have that linked to a DVI adaptor driving a Philips 20" widescreen monitor in portrait mode (awesome for browsing). I have another, identical Philips monitor and wondered if there was a way of connecting that to the iMac too. Is there such a thing as a DisplayPort Mini-DVI to dual-DVIs adaptor? Can this iMac's graphics card even drive such a set-up? The graphics chipset in the iMac is reported as ATI Radeon HS2600, 256 MB. The main iMac display is 1920x1200 and the Philips display is 1050x1680 (@60Hz, rotated 90 degrees). The third screen would be another 1050x1680 and ideally I'd have it portrait again, too. EDIT: Please let this question stand - it's not a dupe. The current Mac laptops use 'Mini Displayport' connectors, which are not the same as DisplayPort Mini-DVI connectors.

  • Windows DNS Server 2008 R2 fallaciously returns SERVFAIL

    - by Easter Sunshine
    I have a Windows 2008 R2 domain controller which is also a DNS server. When resolving certain TLDs, it returns a SERVFAIL: $ dig bogus. ; <<>> DiG 9.8.1 <<>> bogus. ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 31919 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus. IN A I get the same result for a real TLD like com. when querying the DC as shown above. Compare to a BIND server that is working as expected: $ dig bogus. @128.59.59.70 ; <<>> DiG 9.8.1 <<>> bogus. @128.59.59.70 ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 30141 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;bogus. IN A ;; AUTHORITY SECTION: . 10800 IN SOA a.root-servers.net. nstld.verisign-grs.com. 2012012501 1800 900 604800 86400 ;; Query time: 18 msec ;; SERVER: 128.59.59.70#53(128.59.59.70) ;; WHEN: Wed Jan 25 14:09:14 2012 ;; MSG SIZE rcvd: 98 Similarly, when I query my Windows DNS server with dig . any, I get a SERVFAIL but the BIND servers return the root zone as expected. This sounds similar to the issue described in http://support.microsoft.com/kb/968372 except I am using two forwarders (128.59.59.70 from above as well as 128.59.62.10) and falling back to root hints so the preconditions to expose the issue are not the same. Nevertheless, I also applied the MaxCacheTTL registry fix as described and restarted DNS and the whole server as well but the problem persists. The problem occurs on all domain controllers in this domain and has occurred since half a year ago, even though the servers are getting automatic Windows updates. EDIT Here is a debug log. The client is 160.39.114.110, which is my workstation. 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Rcv 160.39.114.110 2e94 Q [0001 D NOERROR] A (5)bogus(0) UDP question info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x0100 QR 0 (QUESTION) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 0 Z 0 CD 0 AD 0 RCODE 0 (NOERROR) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty 1/25/2012 2:16:01 PM 0E08 PACKET 000000001EA6BFD0 UDP Snd 160.39.114.110 2e94 R Q [8281 DR SERVFAIL] A (5)bogus(0) UDP response info at 000000001EA6BFD0 Socket = 508 Remote addr 160.39.114.110, port 49710 Time Query=1077016, Queued=0, Expire=0 Buf length = 0x0fa0 (4000) Msg length = 0x0017 (23) Message: XID 0x2e94 Flags 0x8182 QR 1 (RESPONSE) OPCODE 0 (QUERY) AA 0 TC 0 RD 1 RA 1 Z 0 CD 0 AD 0 RCODE 2 (SERVFAIL) QCOUNT 1 ACOUNT 0 NSCOUNT 0 ARCOUNT 0 QUESTION SECTION: Offset = 0x000c, RR count = 0 Name "(5)bogus(0)" QTYPE A (1) QCLASS 1 ANSWER SECTION: empty AUTHORITY SECTION: empty ADDITIONAL SECTION: empty Every option in the debug log box was checked except "filter by IP". By contrast, when I query, say, accounts.google.com, I can see the DNS server go out to its forwarder (128.59.59.70, for example). In this case, I didn't see any packets going out from my DNS server even though bogus. was not in the cache (the debug log was already running and this is the first time I queried this server for bogus. or any TLD). It just returned SERVFAIL without consulting any other DNS server, as in the Microsoft KB article linked above.
