Sorry to be so slow in responding.. that exception appears when the
connection between the buildslave and buildmaster has been dropped because of
a timeout. Your system must be under enough load that one side or the other
is unable to get a few CPU seconds every couple of minutes to respond to the

If it keeps happening, you could probably edit the source code to increase
the timeout. Let me know if it's still a problem and I'll track down the file
to modify.
