Description of problem:
On occasion the program will "hang" when doing incremental dumps.
That is annoying enough, but what is worse is that the program cannot
be killed.  It seems that one "hung" xfsdump process interferes with any further
attempts to perform the selected backup.  The only way I have found to
kill these disconnected processes and successfully try to dump again is
by rebooting the system.

Note the two instances of post-kill-attempt xfsdump

I partially got around this problem some time ago by applying a patch produced
by Christoph Hellwig.  See:

http://oss.sgi.com/archives/linux-xfs/2004-05/msg00212.html

Which apparently deals with a memory managment problem.
(The patch is for /usr/src/linux-2.6.5-1.358/fs/xfs/linux/xfs_buf.c)

The cutomized kernel no longer has the xfsdump hanging non-killable,
but the kernel still does crash with depressing frequency during dumps.

Is this considered a user space or kernel problem?

Thank you.

Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
