Since upgrading my server from CentOS 4.5 to 4.6 I've been getting the<br>following error from amanda backups:<br><br>mutilate /home lev 1 FAILED [compress got signal 11, /bin/tar got<br>signal 13]<br><br><br>I was away from the house for most of the end of December and had a
<br>couple of other issues that came up that could have been related but<br>apparently weren't (why is it that several things all go wrong at<br>once?). After getting these other issues resolved I was still getting<br>
the above error. I tried running the following command as root:<br><br>/bin/tar -X /etc/amanda/exclude-list/exclude.txt -cvf - /home | gzip -v<br>-c > /share/dave/Home.tar.gz<br><br>Initially tar would die while attempting to back up one of IMAP folders
<br>that had quite a few fairly large e-mails (some pictures my brother had<br>sent). I removed the larger e-mails and tar proceeded past the IMAP<br>folder that had been the problem only to die later:<br><br>...<br>/home/judy/Judy's Stuff/School/

<br>normally.<br><br>So, is this a tar bug (doesn't like big files now) or is there some<br>other issue like available shared memory that's causing the problem?<br><br>Cheers,<br>Dave<br><br>--<br>Politics, n. Strife of interests masquerading as a contest of principles.

Finally you need to get a stack trace why you need to set the core size limit above the default 0 size with "ulimit -c unlimited" before running the command. You can now use gdb to make a stack trace "gdb <path to exec file> <path to core file>" and type where and type "where" in order to get a stack trace that you can publish in a relevant forum for further examination by developers.
