[Buildbot-devel] twisted.internet.error.ConnectionLost

[Jianjun Mao]

I am trying to make a lower level proxy to reconnect the network when in
poor network.

The connection is:
Buildbot master  <-> Proxy server <-> Proxy client <-> Buildbot slave.

The connection between buildbot master and proxy server is very stable,
same as buildbot slave and proxy client.
I hope this program can drop this frustrated error...
