Important Tomcat oftenly out of order

Hello
We have to restart the tomcat service during the day, because the Analytics is not accessible anymore.
When we look in the tomcat's log file, we found this error message :

File : tomcat7_stambia_prod-stderr.2017-05-11.log

Message : org.eclipse.swt.SWTException: Invalid thread access
+ see join file

Do you know where it come from ?
If we look the performance, we are around 60 % of Process, and 40% of memory.

Thanks

Any answer or similar case ?

Not 100% sure it will solve your issues, but we had a similar case with a customer installation.
They solved it by leaving Tomcat's memory settings to their defaults (empty fields in the Tomcat service configuration). Analytics should work well with Tomcat's default settings.

If you still have memory issues, the usual steps would be to setup an observation of the JVM memory usage (using jvisualvm or jconsole) and making memory dumps when the problem occurs. Then share this information with the Support.

Hello
Thanks for the information.
Do you know where to do so ? I tried a few files without sucess

It depends on the tomcat installation.
See "Tomcat monitor application" here: tomcat.apache.org/tomcat-7.0-doc/windows..._monitor_application
(or in their documentation related to your tomcat version)

Hello
It still fall...

When i search for the error message found (java.lang.OutOfMemoryError: PermGen space)
, i found Lien vers solution ?this :

What do you think about it ?
It is said JIRA is the cause.
And that we should get a bigger MaxPermSize (memory allound to permgen)
Example : MaxPermSize=256m !

Thanks
Virginie

I think it is worth trying
