Server disconnected unexpectedly.

See original GitHub issue

After updating Buck https://github.com/facebook/buck/compare/996fc3c1f0c6415477cbbf76aea005286dc4d6ab...02e709184fbd0534817c1e73f7db71b13093e4dd I’m observing CI build errors with following log:

[ERROR][buck.py:173] Server disconnected unexpectedly: [Errno 104] Connection reset by peer

NailgunException: Server disconnected unexpectedly: [Errno 104] Connection reset by peer

Our Buck CI job makes few sequential buck invocations, this particular one is buck project and build fails pretty consistently on this stage.
