Again, please do not drop the mailing list.  Your email filtering
software is also still stripping out some of the attachments although
I don't really expect that there are any clues in the scripts.

There's nothing that I see that's unusual in any of your logs.  You're
going to have to try to capture the kernel messages at the time of
failure using something like kdump or netconsole.
