Hi, I'm running Bacula 5.0.2 in conjunction with PostgreSQL 8.4.3 (both compiled from the "official" sources) on a Debian Lenny system. The system runs the director, storage daemon and file daemon. The actual storage media are barcode labeled LTO3 tapes contained in a HP Storage Works 1/8 G2 autoloader equipped with an HP Ultrium 920 drive.
I've already followed the instructions in
http://tldp.org/HOWTO/html_single/TCP-Keepalive-HOWTO/
and the corresponding FAQ entry
http://wiki.bacula.org/doku.php?id=faq#my_backup_starts_but_dies_after_a_while_with_connection_reset_by_peer_error
since I came accross this thread, which had been started before I subscribed to
the Bacula users mailing list:
http://adsm.org/lists/html/Bacula-users/2010-04/msg00172.html
I decided to compile the libkeeplive from Source Forge and use the
LD_PRELOAD mechanism in order to make sure libkeeplive.so is always
loaded. Furthermore I changed the sysctl and Heartbeat Interval
settings as described in the referenced FAQ entry.
Disabling accurate backups is not a solution for me since I want
deleted files to be taken into account and I have to run quite a few
long running shell scripts for gathering data via SCP from other hosts
before the actual backup (writing to tape via SD) starts. So, a
workaround for the TCP keepalive problem is absolutely necessary for me.
A status inquiry on the client from within bconsole works without a
problem, but even with TCP keepalive enabled my backup stops after a very short
period of time, as the
log from the Bacula director shows:
