Threads memory management problem with Opennms 19.0.1
Description
I have problem with java threads memory allocation. I try to set java heap size to extremely large size and I got the same errors. I try to set size from 20GB to 60GB for heap. Opennms works several hours after restart and crashes with errors from attachment. I try disable single deamons, but it does not change anything. Opennms monitors about 13K host and 28 oids per host. I changed file system from ext4 to xfs and added RAM from 32GB to 96GB to improve performance, but it did not change anything. When I used Opennms 18.0.1, I never received this errors.
Environment
2x Intel Xeon E5540@2.53GHz, 96GB RAM, RAID10 for RRD and database, CentOS 6.9, Postgresql 9.4, java jdk1.8.0_60.x86_64.
