[1.] Summary
System Freeze on Particular workload with kernel 2.6.22.6

[2.] Description
System freezes on repeated application of the following command
for f in *png ; do convert -quality 100 $f `basename $f png`jpg; done

Problem is consistent and repeatable.
Problem persists when running on a different drive, and also in pure console (no X).

One time, the following error logged in syslog:
Sep 19 04:22:11 mossnew kernel: [ 301.883919] VM: killing process convert
Sep 19 04:22:11 mossnew kernel: [ 301.884382] swap_free: Unused swap offset entry 0000ff00

Sep 19 04:22:11 mossnew kernel: [ 301.884562] swap_free: Unused swap offset entry 00000100

Should not be a RAM problem. RAM has survived 12 hrs of Memtest with no errors.
Should not be a CPU problem either. I have been running CPU intensive tasks for days.

[3.] Keywords
freeze, swap_free,VM

[4.] /proc/version
Linux version 2.6.22.6intelcore2 (root@mossnew) (gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)) #1 SMP Sat Sep 15 00:29:00 EDT 2007

[5.] No Oops

[6.] Trigger
- Create a large number of png images. (a few hundred)

- repeatedly run
for f in *png ; do convert -quality 100 $f `basename $f png`jpg; done

- This might be subjective, but the freeze seems to show up sooner if there is a CPU heavy
process running in the background.
