OutOfMemoryError

[Michael Kohls]

Hello,

we have problems starting Jira after installation on a new Ubuntu 18.04 Server:

java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start0(Native Method) at java.lang.Thread.start(Thread.java:717) at com.atlassian.scheduler.caesium.impl.CaesiumSchedulerService.startWorkers(CaesiumSchedulerService.java:288) at com.atlassian.scheduler.caesium.impl.CaesiumSchedulerService.startImpl(CaesiumSchedulerService.java:272) at com.atlassian.jira.scheduler.JiraCaesiumSchedulerService.startImpl(JiraCaesiumSchedulerService.java:33) at com.atlassian.scheduler.core.AbstractSchedulerService.start(AbstractSchedulerService.java:161) at com.atlassian.jira.scheduler.JiraSchedulerLauncher.proceedIfAllClear(JiraSchedulerLauncher.java:36) at com.atlassian.jira.scheduler.JiraSchedulerLauncher.start(JiraSchedulerLauncher.java:22) at com.atlassian.jira.startup.ActiveServicesLauncher.start(ActiveServicesLauncher.java:56) at com.atlassian.jira.startup.DefaultJiraLauncher.postDBActivated(DefaultJiraLauncher.java:172) at com.atlassian.jira.startup.DefaultJiraLauncher.lambda$postDbLaunch$2(DefaultJiraLauncher.java:146) at com.atlassian.jira.config.database.DatabaseConfigurationManagerImpl.doNowOrEnqueue(DatabaseConfigurationManagerImpl.java:301) at com.atlassian.jira.config.database.DatabaseConfigurationManagerImpl.doNowOrWhenDatabaseActivated(DatabaseConfigurationManagerImpl.java:196) at com.atlassian.jira.startup.DefaultJiraLauncher.postDbLaunch(DefaultJiraLauncher.java:137) at com.atlassian.jira.startup.DefaultJiraLauncher.lambda$start$0(DefaultJiraLauncher.java:104) at com.atlassian.jira.util.devspeed.JiraDevSpeedTimer.run(JiraDevSpeedTimer.java:31) at com.atlassian.jira.startup.DefaultJiraLauncher.start(DefaultJiraLauncher.java:102) at com.atlassian.jira.startup.LauncherContextListener.initSlowStuff(LauncherContextListener.java:154) at java.lang.Thread.run(Thread.java:748)

I installed Jira as mentioned here:
https://confluence.atlassian.com/adminjiraserver/installing-jira-applications-on-linux-938846841.html

The machine has 12GB Ram, there is no other Service installed.

I could send you the full log, but unfortunally your form doesn't have a file upload. Maybe I can send it afterwards?

Kind regards,

Thomas Liepe

Can you check how the limits (number of procs, number of files) are configured for the suer running jira / system in general

Hi,
thanks for your answer.

Unfortunatelly, I already tried this. Rebooted the machine after setting the settings. No success.

Check also your heap size in <JIRA_INSTALL>/bin/setenv.sh

Even though the VM has 12GB, the Jira JVM may not be told to utilise all this memory. Default is 1GB I think

And if you need support from Atlassian, try https://support.atlassian.com/contact/

Hi Jimmy,

thanks for your answer.

I already set the heap size temporarly to 8GB. Default was 2.

When the error occurs, top shows me, that java uses ~1,5GB, so the limit is far from reached.

We only have a starter-license. Unfortunately, Atlassian doesn't gives support for this.
