I have two logstash nodes running with 8 cores each. However, they consistently crash (every 1 or 2 days) with "Too many files open". I've only been able to find cases of this message on ES, has anyone encountered this on logstash?
-bash-4.2# ulimit -n 8192
I worry that this has to do with the performance of my grok filters. Any help or input on how to proceed to investigate ore remedy would be appreciated.
