> Hi. We've been running into errors caused by exceeding the number of file handles recently
on jenkins ( From what we can tell:
> {noformat}
> kern.maxfiles: 12328
> kern.maxfilesperproc: 11095
> kern.openfiles: 11601
> {noformat}
> so it's indeed very close to the system maxfiles. We have tried to pinpoint the problem
but we failed (Robert Muir, Dawid Weiss). Our suspicion is that something else (a different
jail?) is sucking all the resources out but it's hard to tell, really.
> Quesitons/ wishes:
> - could you take a look at the machine's jails -- is maxfiles shared between them or
is it per-jail limit? If it's per-jail then what is eating away so many file handles on lucene.*?
> - would it be possible to bump maxfiles (if the cause of the problem remains unknown)
so that we can proceed with regular builds?
> Any other suggestion you may provide to resolve the problem will be very welcome. We
lsof'ed, sockstated and everything else. Solr/Lucene builds are pretty heavy but the above
situation is present even when no build takes place.
