Hi Bacula enthusiasts,
Since one year ago we implemented for our hosted servers a bacula backup
domain. Since the beginning we have sometimes (regularly on sundays with full
backups) the problem: "Fatal error: backup.c:892 Network send error to SD.
ERR=Broken pipe"
This is an hot issue on this mailing list and commonly the firewall is the
problem. We have done several things as changing TTL's on the firewall side and
implemented the heartbeat line on both of FD and SD.
Heartbeat setting: Heartbeat Interval = 300
It looks like the problem always have to do with a pre-backup-script in this
case "automysqlbackup" and when it run's for at least 15 minutes. Why is the FD
starting a connection to the SD before the pre-backup-script?
Below you find the backup log of one of the failing hosts. We made host01 of
the hostname to make it anonymous.
Hope someone can put us in the right direction!
Best,
Nextpertise
