I grep'ed through the l;ogs of one of my 'cumber' machines
(3.0-current of 0505) and found a lot of those in conjunction with a
corrupt /var FS.

Jun 30 09:00:00 toots /kernel: pid 6653 (atrun), uid 0: exited on signal 11
(core dumped)
Jun 30 09:05:00 toots /kernel: pid 6662 (atrun), uid 0: exited on signal 11
 (core dumped)
Jun 30 09:10:00 toots /kernel: pid 6668 (atrun), uid 0: exited on signal 11
 (core dumped)
Jun 30 09:15:00 toots /kernel: pid 6677 (atrun), uid 0: exited on signal 11 
(core dumped)
Jun 30 09:20:00 toots /kernel: pid 6686 (atrun), uid 0: exited on signal 11 
(core dumped)
Jun 30 09:25:00 toots /kernel: pid 6691 (atrun), uid 0: exited on signal 11 
(core dumped)
Jun 30 09:30:00 toots /kernel: pid 6697 (atrun), uid 0: exited on signal 11 
(core dumped)
Jun 30 09:35:00 toots /kernel: pid 6706 (atrun), uid 0: exited on signal 11 
(core dumped)

and:

/var/log/messages:Jun 30 10:30:00 toots atrun[233]: Cannot stat in
/var/at/jobs/: Bad file descriptor
/var/log/messages:Jun 30 10:40:00 toots atrun[367]: Cannot stat in
/var/at/jobs/: Bad file descriptor
/var/log/messages:Jun 30 10:55:00 toots atrun[668]: Cannot stat in

/var/log/messages:Jun 30 11:00:00 toots atrun[684]: Cannot stat in
/var/at/jobs/: Bad file descriptor                

[lines broken for convenience]


The trouble went away after I rebooted and fsck'ed /var.
