| 01:14.30 | apaapa | can anyone tell me how to make tomcat auto-start during boot in linux platform? |
| 01:15.03 | lyken | apaapa: there are some init scripts around the place |
| 01:15.42 | apaapa | lyken: i got the script but i dunno how to make it work...and where to put it |
| 01:15.58 | lyken | do you know how to install init scripts on linux ? |
| 01:16.05 | lyken | if you dont you should check out how to do that for your distro |
| 01:16.14 | apaapa | ok...thank |
| 01:16.23 | apaapa | another thing is this script ok? http://www.pastebin.ca/887367 |
| 01:18.01 | lyken | assuming you have an init.d like system then it should work |
| 01:19.17 | apaapa | i'm using centos5 ...i guess it have one |
| 01:19.27 | lyken | yer |
| 01:19.53 | apaapa | but i dunno how to install it...asked in centos channel but no one reply :( |
| 01:21.51 | lyken | ive never used centOS |
| 01:22.05 | apaapa | it's ok...thanks for the help |
| 01:22.35 | lyken | id assume it would be something along the lines of redhat though |
| 01:23.04 | lyken | i would also suggest you sit and learn the OS you are deploying your applications on :) |
| 01:24.08 | apaapa | thanks agin |

| 11:37.25 | tijn | hi ppl! i have a problem with my server load, and i'am not sure where to look for the problem, i use Centos 5.0 , JDK 1.5.0 and Tomcat 6.0.13 |
| 11:40.20 | tijn | the problem is: the java process showing in top sometimes peaks a little, but the peak does not lower anymore! so the next peak happens ontop of the previous |
| 11:40.42 | tijn | meaning the load on the machine is now at 200% (cpu) |
| 12:25.07 | djr | and if you restart tomcat? |
| 12:26.53 | tijn | after a restart, it goes well for a while |
| 12:27.01 | tijn | but after a day the same thing happens again |
| 12:27.52 | tijn | atm it has 515 java processes |
| 12:29.28 | tijn | could it be buggy programming of the java apps? (open child threads, but dont close them) |
| 12:32.55 | kjkoster5489 | without more info it could be anything. |
| 12:33.11 | tijn | Hey dont i know you? :) |
| 12:33.16 | kjkoster5489 | ? |
| 12:33.25 | tijn | you wrote a client for zabbix |
| 12:33.25 | kjkoster5489 | From what? |
| 12:33.36 | kjkoster5489 | Yes, I did. An agent, te be precise. |
| 12:33.51 | kjkoster5489 | s/te/to |
| 12:33.52 | tijn | cool :) |
| 12:34.03 | kjkoster5489 | :) |
| 12:34.21 | tijn | funny ;) |
| 12:34.29 | tijn | you are dutch aren't you? |
| 12:34.43 | kjkoster5489 | Yes, you are too, from your name. Am I right? |
| 12:34.48 | tijn | yep :) |
| 12:35.08 | tijn | where are you from? |
| 12:35.08 | kjkoster5489 | Small world. |
| 12:35.13 | kjkoster5489 | Den Haag. |
| 12:35.14 | tijn | yes indeed |
| 12:35.21 | tijn | aha, i am fron Hengelo |
| 12:35.23 | kjkoster5489 | Working in Amsterdam at the moment. |
| 12:35.29 | kjkoster5489 | That's faaar. ;-) |
| 12:35.37 | tijn | hehe |
| 12:35.39 | *** join/#tomcat matt8463 (n=matt@popper.yospace.com) |
| 12:35.53 | kjkoster5489 | 515 tomcat processes or random Java processes? |
| 12:36.03 | tijn | random java processes |
| 12:36.14 | tijn | well, random, it looks forked |
| 12:36.52 | kjkoster5489 | Sounds like a lot to mee. Are you sure they're actual processes and not threads? |
| 12:37.00 | kjkoster5489 | s/mee/me |
| 12:37.21 | tijn | well it shows up in top |
| 12:37.56 | tijn | to be clear, i am not an tomcat/java person i administer the server |
| 12:38.11 | kjkoster5489 | I figured that. :) |
| 12:38.13 | tijn | ;) |
| 12:38.16 | kjkoster5489 | Do you use Zapcat? |
| 12:38.20 | tijn | not yet |
| 12:38.39 | tijn | almost finished the zabbix install on 20 servers |
| 12:38.53 | tijn | after that we will implement zapcat |
| 12:38.53 | kjkoster5489 | Cool, let me know how you fare. |
| 12:38.59 | tijn | will do! |
| 12:39.38 | kjkoster5489 | So you start only the Tomcat and not the forked processes? |
| 12:39.45 | tijn | yes |
| 12:40.24 | tijn | and after a day or so cpu load is 199% |
| 12:40.51 | tijn | is it possible a process is started from within a script? |
| 12:40.55 | kjkoster5489 | If you check with ps, do you have 515 processes or just the one Java process. |
| 12:41.10 | kjkoster5489 | Sure, Java is just an app, like any other. |
| 12:41.25 | tijn | ps shows 1 java process |
| 12:41.27 | kjkoster5489 | Plus, in Java I can call System.exec(...). |
| 12:42.14 | kjkoster5489 | Then it looks like each thread shows up as a separate process in top. This must be Solaris then. |
| 12:42.34 | tijn | nope, Centos |
| 12:42.37 | kjkoster5489 | Ok. |
| 12:43.12 | tijn | i read a mail from a list suggesting threads are started from within the code but not properly closed (parent process will be killed off, but childeren are not) |
| 12:43.18 | tijn | could this be something? |
| 12:43.18 | kjkoster5489 | You can make thread dumps from the Java process and trawl through them to find out what it's doing. |
| 12:43.21 | kjkoster5489 | Hmm. |
| 12:43.29 | kjkoster5489 | Maybe you can even use jconsole for that. |
| 12:43.35 | kjkoster5489 | What version of Java are you using? |
| 12:43.51 | tijn | 1.5.0 |
| 12:44.56 | kjkoster5489 | Try hooking up jconsole and see what threads are running. |
| 12:45.14 | tijn | ok, moment please, i will get a dev guy ;) |
| 12:45.20 | kjkoster5489 | Do that periodically, preferably with a Java dev. |
| 12:45.26 | kjkoster5489 | Sure |

| 12:53.55 | tijn | kjkoster5489, ok i caught a dev person :) |
| 12:54.10 | kjkoster5489 | ool |
| 12:54.10 | tijn | he will have a deeper look into it with jconsole |
| 12:54.33 | kjkoster5489 | There is a threads tab, it will list the threads and their backtraces. |
| 12:54.49 | tijn | ah ok, that should be usefull :) |
| 12:54.50 | kjkoster5489 | Look for huge numbers of identically-named threads. |
| 12:55.27 | tijn | ok, and if there are alot, what could be wrong? |
| 12:55.28 | kjkoster5489 | The dev may be able to tell you what threads are harmless and of which threads he never expected there to be so many of. :) |
| 12:55.38 | tijn | ah ok |
| 12:55.54 | tijn | and via the backtrace we can identify where the threads come fron |
| 12:55.57 | tijn | from* |
| 12:56.06 | kjkoster5489 | Maybe you have a worker thread that does not finish on time, then a second is started for the same job and so on. |
| 12:56.11 | kjkoster5489 | Yes. |
| 12:56.20 | tijn | aah ic |
| 12:56.23 | tijn | nice! |
| 12:56.28 | tijn | thnx for your help! |
| 12:56.31 | kjkoster5489 | Its heavily application dependent what is good and what is bad. |
| 12:56.37 | kjkoster5489 | I'm curious what you find. |
| 12:56.42 | tijn | me too :) |
| 12:56.45 | tijn | i will keep in touch |
| 12:56.51 | tijn | you are always on this channel? |
| 12:56.56 | kjkoster5489 | Using zapcat you can plot thead count in Zabbix. |
| 12:57.06 | kjkoster5489 | So you can see when it expoldes. |
| 12:57.10 | kjkoster5489 | explodes. |
| 12:57.17 | kjkoster5489 | Yes, usually. |
| 12:57.27 | kjkoster5489 | Or on #zabbix |
| 12:58.43 | tijn | ah ok |
| 12:59.20 | tijn | well, i am going to hunt down some devs and discuss this info with them ;) thnx! |
