Hi List
I am using bacula version 2.2.5 and have a problem where a job, the
fourth out of five, just grinds to a halt right after the last file. The
job does not reach full completion and stalls. This job has been fine
for months but after upgrading to bacula 2.2.5 this problem has started.
The job sometimes does complete and sometimes not so the error is
intermittant. I have a new tapes for a couple of days so I can rule out
worn tapes and the drive heads have been cleaned thouroughly. As
mentioned the error only occurs on this job the fourth out of six. The
speed of the data transfer slowly declines over a number of hours from
about 11MB/s to 300 KB/s when really the job should have completed and
the final job started and completed. There are no cron jobs set during
the backup period or any other obvious underlying system problems.
Restarting the bacula services sometimes and sometimes does not solve
the problem temporarily. Network connections between the bacula server
and client are stable and not through a firewall, 100MB/s tcp LAN with
no other heavy network load during the job time frame.
Here is the job message after I have manually cancelled it on a brand
new tape:-

I have not upgraded the client software, as I said the other jobs have
caused no problems at all with the same client version combination.

}

Max Run Time = 40m
}
