All,
I've got a Bacula installation that has a peculiar problem that I need
some assistance in resolving:
Once a job starts (as in, gets accepted by the SD as a job to run), I
am unable to cancel it. Using the "cancel" bconsole command, I
receive the following output:
*cancel jobid=205
2001 Job fileserver2_Backup.2010-12-09_09.39.25_04 marked to be canceled.
3000 Job fileserver2_Backup.2010-12-09_09.39.25_04 marked to be canceled.
You have messages.

The director then treats this job as canceled, but both FD and SD
treats it as if it is still running. Canceling a job before it
becomes runnable (say, if the SD has exceeded the Max Storage Jobs
directive) works perfectly fine. As a side effect of this problem,
the SD will keep the backup device open indefinitely. I have to kill
both the FD and the SD in order to reset things back to a working
state following a cancelled job.
I'd appreciate some guidance on how to go about diagnosing and
resolving this problem.
Thanks!

Some configuration notes:
I'd be happy to provide additional configuration details (such as the
contents of the bacula-*.conf files) if anyone thinks that would be
helpful.
The director and SD are running on the same machine. The example
output above was generated by a FD running on a different machine from
the director and SD, but I can replicate the problem on a FD running
locally on the same machine as the director and SD, as well as any
other FD in my installation.
uname -a outputs "Linux director.f.q.d.n 2.6.18-194.8.1.el5 #1 SMP Wed
Jun 23 10:58:38 EDT 2010 i686 i686 i386 GNU/Linux"
Bacula was built from source, using the following configure:
./configure \
-sbindir=/scratch/bacula/bin \
-sysconfdir=/scratch/bacula/etc \
-enable-smartalloc \
-enable-batch-insert \
-enable-largefile \
-with-mysql \
-with-openssl \
-enable-conio \
-with-working-dir=/scratch/bacula/var
...which resulted in the following summary output:
