Backups (tar and gzip) fail due to auditd -- please help


I have a regular backup that runs every 4 or 5 days. Essentially it tars up everything into multiple tar files. I then tar the tar files and gzip them. After gzipping them, I copy off the file to a NAS drive. This was working great until a couple of days ago. Now, either when the backup is gzipping or copying the file to the NAS drive it fails. The script completes, as it updates an "elapsed_time.txt" file; however, the backup is missing.

I believe that the failure occurs during the mv command where I move the backup from the temp location to the NAS drive.

The only hints I can find as to what may be the cause is this line in my /var/log/messages (actually, this message is repeated 10-50 times):

kernel: audit(1194392290.234:89): REJECTING access to capability 'sys_resource' (syslog-ng(2347) profile /sbin/syslog-ng active /sbin/syslog-ng)

I have also seen the following:
auditd[1921]: Audit daemon has no space left on logging partition

I tried clearing up log files, but I can't seem to fix the issue.

I disabled auditd during the backup, but it didn't make a difference:

I am running:
OpenSuse 10.2

Thanks in advance.

If you have an out of space problem then it may not be only triggered by an increase in log space usage. You are creating a lot of huge temporary files and the out of space condition could be caused by different files on different backup attempts.

I think that you should look for an out of space condition on several partitions. Check the partition where /tmp resides. Check the partition where you are creating the tarballs. Check the NAS partition. Also recheck the partition where the log files reside.

You can check the amount of available space with the df command:
