[Cruisecontrol-user] "Too many open files" when cruisecontrol left running for days

[Rob J. <ro...@ni...>]

I have my idle loop set to check once every 60 seconds (we want to have
timely builds after a checkin to our trunk).  I checked in around noon
today (the first person to do so in about a week =96 most people are
working on their own branches), and cruisecontrol didn=92t email me after
10 minutes (our normal build is around 5 =96 we=92re early in development).
I checked cruisecontrol.log and saw this:

Is the p4 task leaking file handles?  Or is some other part of
cruisecontrol leaking file handles?  Anyone else seen this exception?

 

Cheers,
