I'm running GNUGK 2.2.1 in full proxy mode and
I'm getting lots of sockets stuck in the close mode,
waiting for the last packet or two to be read.
I'm running CentOS3 with Dual Opterons, 4 GB of ram total.
Hopefully, someone can identify the problem and a solution.
As a side effect, memory utilization goes up since the threads
still have cleanup left to do - hopefully.
I peaked today at 127 calls and had a total of 306 sockets at that time.
When my traffic drops to just a few calls, there are about 70 sockets left
stuck.
They seem to eventually get cleaned up, there's no way to tell the age of
the
"CLOSE_WAIT" sockets.
I've included gnugk.ini portions, netstat -an output, and level 5 log snipet
of
release complete - no further processing occurs beyond this for a given
call.
I re-started the gnugk yesterday, to get a clean start for last night.
Thanks for any help!
