Not sure why opennms services might crash, never experienced that issue.

I had restarted opennms multiple times yesterday, only one more router got its snmp interfaces properly discovered/provisioned.  Once it is provisioned, the resource graphs are working properly, as collected and instrumentation appear to work.  Any suggestion about what version of "STABLE" opennms shall I use?

Can you check your hard and soft limits?  Do you run on Linux or 
FreeBSD?  On Linux /etc/security/limits.conf or /etc/security/limits.d/, 
FreeBSD /etc/login.conf I guess.  The alternative with systemd would be 
to set LimitNOFILE=65536 in opennms.service or make a snippet with extra 
option.

OpenNMS is has rolling release cycles, so the latest 21.1.0 works just 
fine to me.

One more thing, can you check JDK version you are using?
