Thanks a lot. It helped, I noticed the error in the solr console log.
cat solr-8983-console.log

Running OOM killer script for process 24431 for Solr on port 8983
Killed process 24431
Wasn’t sure if it would help, but I increased the max memory allocated for
Metaspace size from 64 to 128. Would continue to monitor and see if it works.
Is there any ideal memory space that is suggested?
SOLR_OPTS="$SOLR_OPTS -XX:MaxMetaspaceSize=128m"
Thanks

If this has been working fine for a while and suddenly started this
behavior my first suspicion would be excessive GC, i.e. you've been adding
docs and your heap is no longer adequate. If Java needs to do a
stop-the-world garbage collection you can get these kinds of errors.
So I'd enable GC logging on my Solr instances (and ZooKeeper) and then use
something like GCViewer to figure out whether I have excessive
stop-the-world pauses first.
Best,
Erick
