I had a very similar problem, with it getting worse over time.  What I
found was that my backuppc server was low on RAM.  When multiple backups
were running, the system would thrash and page heavily which led to
network timeouts and the connection to be reset.  Very frustrating to
debug only looking at the logs.

Might be worth double checking you have enough free RAM during your busy
periods.

HTH,
