"-athlonxp" is just a descriptive name, for me to differentiate my

Hi Evaldo,

Do you have swap space available when this happens?

Absolutely. this box never gets 500M swap used. highest I ever saw is
400M on VERY HIGH activity (which happened only once, when we had a task
force going on here). right now, swap usage is 3M
I just added 500M more swap to it, just in case (swap partition)

Oh. and I had memtest86 run the 'full test' for 4 days non-stop before
going production ;)

This is probably happening because you ran out of swap space. Adding more
will help.

Check for application memory leaks.
