What do you get when you run the following command?
dir /usr/local/nagios/tmp/nagios* | wc -l
LSOF returns entries for files that have already been deleted on my
system...
nagios 4034 nagios DEL REG 3,1 1141972
/usr/local/nagios/tmp/nagios2e8Q7h
Looks like the kernel must keep references to these files even after
they've been removed. This appears to be true based on an article I
just found:
http://www.linux.com/article.pl?sid=06/10/30/1652211
There's probably a way to tweak the kernel's behavior into immediately
releasing these files once they've been deleted. Normally the kernel
keeps references to deleted files in memory (at least for a while) until
the process that deleted them exits.
Any kernel gurus out there have a solution to this?
