[opennms-discuss] OpenNMS partially unusable after upgrade 18.0.3 -> 19.0.1

[Guenther S. <gue...@sm...>]

Hello together,

 after the OpenNMS upgrade to 19.0.1 we have lost some parts of the GUI,
 i.e. the provisioning requisitions („cannot retrieve requisitions,… try again later“)
 and the resource graphs as well as the KSC reports.
 
 Reviewing the resource usage, I have increased the max. number of file handles
 to 20480 as well as the Java heap to -Xms2g -Xmx10g but in vain:
 there are still lots of "java.lang.OutOfMemoryError: unable to create new native thread“ messages…
 The nice fact is that the other operations like monitoring and BSM work well ?!

 Does anyone experience the same issues?

Regards,
 Guenther

BTW: the environment is
- CentOS release 6.9 (Final) (virtualized guest w/ 12 GB RAM)
- postgresql 9..4.8
- java 1.8.0_131
