[Buildbot-devel] Buildslave disconnects

[Mark MacVicar]

Our buildmaster and one slave is running on an instance of VMWare, the
other slave is a dedicated pc.

I'll see if I can track it down to the TCP issue you mentioned or try
to get some better hardware.

I tried increasing the timeout for each slave to 1200 seconds but they
are still reporting "BotFactory.checkActivity: nothing from master for
1307 secs" then they reconnect almost immediately.

I think there might be an update to Twisted. I'll try updating that too.

Thanks for you insight,

Mark MacVicar
