The OS is a bit old right now, from Sept 20th -STABLE sources, but ...
I'm getting a weird circumstance with clients running AOLServer and
OpenACS 3.2.5 ... after a few days of running, the process no longer
responds to HTTP requests, and the logs fill up with a whack of 'out of
file descriptor' messages ...
limit on the machine shows I have "descriptors 11095" available ...
and using lsof on one of the processes that as restarted on Thursday shows
that ~424 files opened, out of which there are 388 KQUEUE:
nsd8x 65198 nobody 46u KQUEUE 0x92599b00 count=0, state=0
nsd8x 65198 nobody 47u KQUEUE 0x915d4400 count=0, state=0
nsd8x 65198 nobody 48u KQUEUE 0x8fb8b100 count=0, state=0
Checking another one that has been running longer:
mars# lsof -p 98527 | wc -l
1046
mars# lsof -p 98527 | grep KQUEUE | wc -l
1009
What are these KQUEUE files that are open? Is there a 'leak' maybe, where
they aren't being closed properly?
Checking another server, with -STABLE current to Jan 6th, there still
shows >90% of files opened being these KQUEUEs:
neptune# lsof -p 84915 | wc -l
456
neptune# lsof -p 84915 | grep KQUEUE | wc -l
420
Thoughts?
