[Buildbot-devel] Win32 Slave Stability Issues?

I am currently working on implementing a buildbot system for all our 
companies products, which are available for multiple operating systems 
ranging from windows to different kinds of unix/linux and macosx.
For that i have deployed a linux based buildbot master server and 
various client systems, triggering different builds depending on 
checkins to subversion repository.
Most of the platforms are working just fine however i am experiencing a 
lot of problems with our WIN32 buildslave. Everything is working fine 
for that one as well if buildbot has to do only 1 build in parallel, but 
for some checkins there will be about 5 to 6 builds being triggered on 
the same buildslave. Whenver the WIN32 buildbot starts a third buildjob 
in parallel (sometimes even for the second one) it disconnects for about 
20 Seconds and if it comes back it will have marked all columns related 
to that slave with "slave lost messages". The intterupt message for that 
case is:

[Failure instance: Traceback (failure with no frames): 
twisted.internet.error.ConnectionLost: Connection to the other side was 
lost in a non-clean fashion.


Did anybod else experience similar issues with WIN32 slaves? I am 
willing to help with debugging, but only have very little experience in 
programming python/twisted. I already changed windows system from WIN/XP 
to Server 2003  and a different hardware but this seems to have no 

Thanks in advance for any help on this,

Markus Kramer
