The Tomcat server installed on mylar.eclipse.org has been down at least 2 times recently. Based on our conversation on the dev call today, neither Steffen nor I stopped it. Steffen said that they rebooted the machine once, so it could just be that the machine has been rebooted a couple of times. We need to figure out why Tomcat is stopping (or crashing) and probably set it to start running when the machine is rebooted. I wasn't sure what component to put this under, so I just picked monitor. We're using the Tomcat server for the monitor usage stuff and for some Jira stuff.
It appears to be down again? I'm getting a "Bad Gateway" message.
Yes, it is not running. From catalina.err: 30/03/2007 19:41:17 18447 jsvc.exec error: Service did not exit cleanly Let's try an upgrade to the latest JDK and Tomcat version.
Hi Steffen, Did you update the server? or should I? thanks.
I'll do it on Friday unless you want to do it before that.
Updated as per comment #4. Please reopen if Tomcat fails again.
Marking as resolved.
Tomcat was just down again... I checked the uptime of mylar.eclipse.org in case Tomcat is just going down because the server is being rebooted, but the server has been up for 58 days. I restarted it, but we should figure out why it keeps crashing.
Tomcat is hit by the OOM killer. # grep Memory /var/log/messages [...] May 5 12:09:56 mylar kernel: Out of Memory: Kill process 4493 (java) score 36291 and children. I have limited the Java heap memory to 192 MB for now but getting more memory (or at least some swap) for the machine would be prefereable.
Now mysql is suffering form this. May 14 15:05:27 mylar kernel: Out of Memory: Kill process 31779 (mysqld) score 31265 and children. I see what appears to be two instances of tomcat running on mylar.eclipse.org?
Sorry, I think I started the second instance, not realizing you were working on the server at the same time. I think we should configure JIRA to use mysql as well instead of the in memory database.
I made a few changes to the server setup: * Downgraded Tomcat to 5.5.23 since I could not get JIRA to run on 6.0.10 without getting crazy amounts of logged errors * Upgraded JIRA to 3.9 * Switched JIRA database from hsql to mysql Meghan, I copied the monitor webapp to the new Tomcat directory. Please make sure that everything is in place (a test upload of my usage statistics was successful). In addition I have contacted the Eclipse webmaster and asked for additional memory for the server.
I have reduced the number of pre-forked apache processes which should help save some memory as well.
