3 things that have given me grief due to the windows FD stopping or being

a) buggy network driver--in one case I was able to update the driver to fix.
I'll second that one. I have had several occasions of a buggy NIC driver
causing the TCP connection to be dropped. In all cases it was fixed by
an updated driver, or by turning off the NIC driver's power management
features. Particularly for laptops, it seems unfortunately common for
the driver to turn off the NIC to save power, even though there is an
active TCP connection. Web browsers and such simply re-connect, so the
dropped connection isn't noticed. But TCP connections for Bacula may be
open for quite some time, so Bacula is more sensitive to network problems.
The only reason I'm ruling this out is that the bacula-fd service dies
when it's just sitting idle, usually dying well before the director
makes contact to initiate a backup request. All other network seems
okay and the person that uses Quickbooks never has issues connecting,
etc.
I'll check further but at this time, I've installed the bacula-fd
client on several other machine of same OS and architecture/hardware
and those are not dying. It's starting to point to some service or
process I'm overlooking perhaps killing it or maybe just a bad
install. I might start by reinstalling bacula and see what happens
then.

b) bad network switch or network port
c) infection with a virus/malware that was using up the "max tcp
connections". Check the event log for that error.
d) regex in the fileset had a bug but that's been fixed around bacula
version 2.5 or so. Along the way I learned that regex was slower to
process than wilddir and wildfile so I stopped using it for windows
filesets anyway.
In all cases these issues caused the windows FD to stop during a backup, so
I hope this helps but if not, you may have to turn on debugging in the FD
and cross your fingers that it happens and logs what went wrong.

I can't seem to figure out what's going on because I've never
encountered this issue when backing up a Windows XP client with the
latest version of Bacula.
I have no problems backing up the client but the file daemon
unexpectedly dies randomly, usually before a backup is even scheduled.
The error I'm seeing in the event log goes something like this:
Bacula Error: /home/kern/bacula/k/bacula/src/lib/bsock.c:518
Read error from Director daemon:<hostname of my director>:9101:
ERR=Unknown error
Above that it complains about local computer and registry info or
message DLL files to display messages from a remote computer, use
/AUXSOURCE=flag to retrieve this description, see Help and Support for
more details.
Anyone encounter this? Is this machine missing something? I'm not a
Windows guy, more of a Unix guy. Everything seems to work okay when I
restart the FD service and backups run without issues. I have backups
kick off at like 7pm and it always seems to die before 3 or 4pm. No
one really remotes into this machine, it's a Quickbooks machine and
only shares out the Intuit QB stuff to the HR persons machine.
Any other info I can provide if necessary. I couldn't seem to locate
this type of issue in the mailing list archives.

No ideas from anyone? Now it seems to die without any reports in the
event viewer or logs.
