Backup failure due to full-text indexing

Hi,
Sometimes, I got the following error while trying to perform a database
backup.
This backup is done on a regular basis using a maintenance plan.
There is a full-text catalog in the database and there must be a conflict
somewhere.
Any idea?

IIRC, this is solved in SP1.

SP1 is already applied on SQL Server 2005.
Displayed version number is 9.0.2047.
It is running on two cluster nodes (Windows Server 2003 R2 Enterprise x64
Edition).

Actually I just realized we get this error message every time we do a
transaction log dump. This error seems to be a warning message more than
anything else.

Thank you for your replies!
There is another error message in the maintenance plan history I didn't see
before.
It seems that the fulltext catalog is offline sometimes which would explain
why the backup could not be done.
But what could turn off the fulltext catalog?

Executing the query "BACKUP DATABASE [BihrOnline2_commerce] TO  DISK =
N'K:\\BOL_BACKUPS\\BihrOnline2_commerce\\BihrOnline2_commerce_backup_200609141600.bak'
WITH NOFORMAT, NOINIT,  NAME = N'BihrOnline2_commerce_backup_20060914160012',
SKIP, REWIND, NOUNLOAD,  STATS = 10  " failed with the following error: "The
backup of the file or filegroup "sysft_Bihr_FTC" is not permitted because it
is not online. BACKUP can be performed by using the FILEGROUP or FILE clauses
to restrict the selection to include only online data.  BACKUP DATABASE is
terminating abnormally.". Possible failure reasons: Problems with the query,
"ResultSet" property not set correctly, parameters not set correctly, or
connection not established correctly.

Not really. The fulltext catalog is working well and the maintenance plan is
working sometimes.
I think that a process is using the fulltext catalog while a rebuild occurs
for example.
In this case, the rebuild would fail and the catalog folder would be erased.
Thus, the backup cannot be done because the fulltext catalog filegroup is
now "OFFLINE".
Am I correct?

I'm not sure. I opened a support incident on this case with Microsoft. We
were getting catalog corruption errors but these were due to something else.
Microsoft wanted us to run a debugger for them and send them the dump but we
were unable to do so. We also run filemon to figure out what was trying to
open the file and it was SQL Server. Microsoft did tell us it was fixed in
SP 1. We still get the errors.

I can reopen the case and get more info for you if you want.

Thanks a lot. You are really nice.

I tried something else:
1) Rebuild the fulltext catalog before backup database
2) Shift the backup log after backup database (it was starting at the same
time before)
3) Run filemon to check which process is accessing the fulltext catalog

Filemon indicates that only sqlservr.exe is accessing the fulltext catalog
when rebuild and backup occured.
Right now, the last backups are succesfull. I hope this will continue and it
may give some hints.

Everything is working fine now.
Rebuilding the fulltext catalog everytime, just before the "backup
database", seems to solve the problem.
