Comment (by Schenker):

 So, the buildbot executes a build and comes to a step on which executes a
 shell script. The master stops responding not only to the slave - it stops
 responding at all. Here is a log output from master/twistd.log:

 As we see, till 20:37 it works (it connects to the svn as scheduled) but
 in one moment it stops. 12 minutes later (as we can see in the slave log
 from the previous post) the slave identifies that the master has gone away
 and they break the connection.

 The same build on the same server works without a problem with buildbot
 0.7.12, but after I upgraded to a buildbot 0.8.* it acts like that (I
 built the new buildbot, then ran a ''buildbot upgrade-master'' and
 ''buildbot upgrade-slave'').
