[Python-Dev] Buildbot - "slave lost"

Does Buildbot retain a constant TCP socket to its server? I'm seeing this: http://buildbot.python.org/all/builders/AMD64%20Debian%20root%203.3/builds/0 """ Results: Retry exception slave lost """ I have two internet connections; one is faster, but tends to drop socket connections after a few hours, and the other is a bit slower but more reliable (as long as the connection doesn't go idle for too long - neither of my upstreams is particularly MUD-friendly). Would it help to set a routing rule to send traffic to python.org:9020 via the connection that won't drop out? ChrisA
