Running tracd on Win2K doesn't clean up TCP/IP sockets causing full buffer

I have Trac 0.7.1 running on Win2K Pro. Runs well for about a week and then I get this on new or updated tickets.

I am serving subversion via svnserve and trac via tracd.

A reboot works to relieve the symptoms.

See the traceback below for more details.

Milestone: 0.8

A quick google hinted that this might be because windows has run out of TCP/IP socket buffers because too many connections are open at once.

Is it enough to just restart tracd or is a full system reboot required?

If simply restarting tracd isn't enough, your windows installation might have a nasty resource leak and you probably need to install some windows service pack or similar to fix this leak…

I have tried simply cycling tracd. It doesn't correct the issue.

Additional information: Both svnserve and tracd are running as services using FireDaemon. The FireDaemon services "call" a batch file each.

Summary: New or Changed Ticket causes error when trying to send notification emailRunning tracd on Win2K doesn't clean up TCP/IP sockets causing full buffer

Changed the summary - the bit about notifications is really just the symptom of tracd running unclean on Windows.
