Every so often, running a parallel set of fabric jobs, I get:

ERROR:ssh.transport:Exception: Mismatched MAC
ERROR:ssh.transport:Traceback (most recent call last):
ERROR:ssh.transport: File "build/bdist.linux-x86_64/egg/ssh/transport.py", line 1529, in run
ERROR:ssh.transport: ptype, m = self.packetizer.read_message()
ERROR:ssh.transport: File "build/bdist.linux-x86_64/egg/ssh/packet.py", line 356, in read_message
ERROR:ssh.transport: raise SSHException('Mismatched MAC')
ERROR:ssh.transport:SSHException: Mismatched MAC
ERROR:ssh.transport:

Any idea what causes this and how I can stop it?
