SOLR crashing during Bulk Indexing
I've completed a rehearsal upgrade to 13.0.2.4 and kicked off a full re-index. In the past, this has been a low risk task that churned away for hours until completion. I've index 850K objects out of 1M but was fighting with Solr to keep running. Rate initially was 2200/min which I guess is good. I have not changed any of the default memory settings. System has 8GB of ram and plenty of HD space. I did not see any areas filling up. I checked the obvious logs but could not find any glaring error messages when it shutdown. I just would notice that I would see failed jobs in the Index Administrator and when I checked, the solr process had ended. I restarted it and resumed but would stop for some reason maybe 1/2 hour later.
When its running, I am able to search and can see Classification Search so I know its functioning. I did see a curious issue with text preview on documents where it showed only name and number. (see https://www.ptc.com/en/support/article/CS249768?source=search) which indicates to reindex again. No problem since this is a rehearsal but still strange.
Looking to see what I should be looking for in the logs as an indicator to why its stopping. I suspect memory issues but did not see any out of memory messages as I would expect. RHEL 9.2 SELinux. Noting issues from previous where I was not able to run this vis systemctl as root (running as another user). I had to start manually as that user from shell each time.
