Hi @kofop,

Seems the issue mentioned (QCCR2A83377) was fixed in A.10.40. Support confirmed it and my own tests confirm it. So upgrading to the new version is considered safe.

I asked them to review/update the documentation accordingly.

Regards,
Sebastian Koehler

Hi,

It's a strange news, because the patch what you sent  me is not solve the problem on 10.30 (but ok, it's solve the high open file number problem). I found a workarond what looks like changeing something (4 days ago): I installed the patch, and I changed the xmx/xms from 2048m to 4096m in /opt/omni/AppServer/bin/standalone.conf, and restarted the processes:

JAVA_OPTS="-Xmx4096m -Xms4096m -Xss228k -XX:NewRatio=2 -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=512m -Djava.net.preferIPv4Stack=true"

The old logs:

Hello @kofop.

    If the larger memory sizes fixed your problem, then 10.40 and later releases should not have this issue since the default memory values have now been increased.

Thanks,

Shishir
