I forgot to mention that during my debugging, I did have "Heartbeat
Interval" set to 10 on the Client, Storage, and Director resources. The
same error still occurred... Very odd.

$20 you have the other bacula comm channel failing due to timeout of
the state on a forwarding device. Dropping spool sizes is only
increasing the frequency of communication across that path. You will
likely see this problem solved completely by setting a short duration
keepalive in your bacula configs.

I just encountered a similar error in RHEL 6 using 5.0.3 (on the
server
and client) with Data Spooling enabled:
10-Jun 02:06 srv084 JobId 43: Error: bsock.c:393 Write error sending
65536 bytes to Storage daemon:srv010.nowhere.us:9103

10-Jun 02:06 srv084 JobId 43: Fatal error: backup.c:1024 Network send
error to SD. ERR=Broken pipe
The way that I made it go away was to decrease "Maximum Spool
Size" from
200G to 2G. I also received the same error at 100G and 50G. I ended up
just disabling data spooling completely on this box since small spool
sizes almost defeat the point of spooling at all.
I've also been seeing some sporadic tape drive errors recently,
too. So
that may be part of the problem. I will be running the
vendor-suggested
diags on the library (Dell TL4000 with 2 x LTO-4 FC drives) in the
next
couple of days.
Plus, this is a temporary SD instance that I will eventually
migrate to
new hardware and add large/fast SAN disk to for spooling. This should
explain the reason for the small spool size settings... This box only
has a 2 x 300 GB drive SAS 10K RAID 1.
It'd be nice to see if anyone else has received this error on a
similar
HW/SW configuration.
