[Buildbot-devel] Windows Slave Hanging

[John Pye]

Hi Alan

I had similar problems with a buildslave on windows XP. Possibly due to
orphaned processed due to the way I had been runnning Python via a batch
script that was invoked by srvany.exe. Not sure that this is the problem
you're seeing.

But perhaps the following notes might point to some things you could try:
