So it wouldn't surprise me you get this over wireless. I've never been able to make a reliable test-case for it to ever properly diagnose the issue. -----Original Message----- From: Kern Sibbald [mailto:k...@sibbald.com] Sent: 03 March 2011 06:07 To: bacula-devel@lists.sourceforge.net Cc: Dan Langille Subject: Re: [Bacula-devel] overly sensitive FD->SD comms On Thursday 03 March 2011 03:05:21 Dan Langille wrote: > Tonight I was doing a backup of my laptop over its wireless connection. > The connection blipped.

Bacula was transmitting data in one direction or the other and ssh was not.

If the comm line breaks while during a transmission whether it is ssh or Bacula, the connection will be dropped -- unless ssh has special code to either ignore errors or re-establish a connect, which from what I have seen of ssh code is not the case.
