New description:
I got this failure on an AMD Opteron 248 based machine running Ubuntu
10.10. The machine has 1 GB RAM and 3 GB swap, but after checking the
memory usage, and checking system logs, I'm convinced the lack of RAM is
not part of the problem. {{{/var/logs/syslog}}} shows no error messages
and using procinfo and top I can find nothing to indicate what might be
causing this failure.
I wonder if this is specific to the Opteron.
