So I come into work today, and the webserver we operate (we do web
development for about two dozen clients) is unresponsive and "weird".
SSH won't connect, then it will. Basic commands (ls!) bitch about too
many open files. And Plesk can't even tell me how much memory is free
all the time.
Eventually, I'm able to get the machine rebooted, and all returns to
normal. But before it went reset, I noticed a hell of a lot of
/usr/lib/pkgconfig/../../bin/mono /usr/lib/pkgconfig
in the 'ps ax' command. My conclusion: Something fork-bombed and ate
up all the available open-file handles.
Any thoughts as to what would cause that command line? Maybe it was
truncated to fit the terminal, but what would try to call its way out
of the pkgconfig directory? And how do I prevent it from recurring?
Box is Fedora Core 4. The only .net stuff we have, to my knowledge, is
a few .aspx pages we developed for testing, then decided it was better
to use a windows development host for people who wanted to host their
final sited on Windows.
