I do have a ticket in with our systems team to up the file handlers

No, but that often needs increasing too. I think you need to increase
the process limit even if that's not the cause of this particular problem.
Had another thought. Either of these limits can cause completely
unpredictable problems with Solr. The open file limit could be the
reason for these issues, even if you're not actually hitting the process
limit. As I mentioned before, I would expect a process limit to cause
Solr to kill itself, and your other messages don't mention problems like
that.
The scale of your Solr installation indicates that you should greatly
increase both limits on all of your Solr servers.
Thanks,
