> Hello, When launching solr (Ubuntu 16.04) I'm getting:
> *
> **
> *** [WARN] *** Your open file limit is currently 1024.
> It should be set to 65000 to avoid operational disruption.
> If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false
> in your profile or solr.in.sh
> *** [WARN] *** Your Max Processes Limit is currently 15058.
> It should be set to 65000 to avoid operational disruption.
> If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false
> in your profile or solr.in.sh
> This appears to be related to a known bug in [#Ubuntu]

> If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false

> Waiting up to 180 seconds to see Solr running on port 8983 []
> Started Solr server on port 8983 (pid=2843). Happy searching!
> cd proc# cat 2843/limits:
> Max processes 65000 65000
> processes
> Max open files 4096 4096 files
>
> The problem persisted after upgrade to Ubuntu 18.10
> Any other solution would be appreciated.
> Otherwise can you please tell me what are the likely consequences of the open
> file limit?
