[Buildbot-devel] exception slave lost

[Ben Hearsum]

Because Buildbot requires a constant connection between master and slave, many things can cause this. I've seen this happen for at least the following reasons:
* Temporary network connection loss or slowness.
* Load so high on master or slave that keepalive can't happen

While it won't help fix the root cause, you may want to consider putting this patch on your master(s), which will set RETRY for builds like this: https://github.com/buildbot/buildbot/pull/937
