What does this command say on your system?
% sysctl kern.maxfiles kern.maxfilesperproc kern.openfiles
You may have exceeded the maximum number of open files
in the system. Maybe some ill-conceived program that doesn't
close non-needed connections, files, etc is at fault? It's easy
to open more and more files, and to gradually fill the open
files descriptor table in the kernel this way.
-cpghost.
From knowing that you have too many files open you can increase the
maxfile numbers - but if you want to know what uses them try this -
lsof -n | awk '{print $2 "\t" $1}' | sort | uniq -c | sort
lsof outputs open file info, awk then gives us the PID and proc name
which gets sorted and uniq gives a count of each which we sort to have
the largest file count at the bottom of the list. What you end up with
is a list of two numbers and a name - count of files open followed by
the PID and proc name that has them open.
The catch is that it also includes network connections (I know how to
list only network but not sure how to exclude them)
ps ax | grep PID
will show you the full program name if it has been shortened.
lsof -p PID
will show all the open files for PID
Not sure if this is the best way but it works for me.
