Re: os-linux/5525: Many sockets left in CLOSE_WAIT, many apache children hang

[Andy <an...@nethernet.com>]

sorry, i guess i should clarify myself.

Before i submitted a bug report i looked at the previous ones. Bug reports
5412, 4984, and 2386 all seem to have the same symptoms, but they are all
on solaris machines. I have tried without all the 3rd party modules, and
removing them does not help. Running GDB on a child results in the
following output:
