Comment 16 for bug 260171

So this morning I got an unexpected clue as to what might be causing this: I had an ssh process connected to bazaar.launchpad.net from yesterday -- and its parent was the bzr-notify process. Now, this may be bug #335180, or just the fact that bzr-notify doesn't run the cycle collector very often, but if this affects more than 25% of Canonical employees even, it could be responsible for a large enough number of apparently stale processes on the server.

I've just sent off to ec2test a change that will disconnect connections that are idle (no traffic in either direction) for more than an hour, which will hopefully kill the problem off once and for all.
