Description Igor Lvovsky 2011-06-14 08:45:01 UTC 
Description of problem:

In vdsm-4.9 code we use multiprocessing.Pipe to communicate with subprocesses.
In several scenarios when we trying to run sufficiently large amount of VMs, the pipe ends raise the exception: "handle out of range in select()".
Actually, it's kind of regression from vdsm-4.5 (we didn't use multiprocessing in vdsm-4.5)

We found same issue (including the patch and reproducer) in python's issue tracker:
 http://bugs.python.org/issue10527
