Once I get up in the morning I open a terminal and run tail on the
syslog. The system is on 24/7 though without the load of Evo or
Firefox. The latest oom, see the link, happened 5h 3m after starting it
this morning after I ran memtest for 11hr 20m.

Logically the next one should happen somewhere between 5 and 6pm
tonight.

Though I stopped clamav earlier freshclam ran and restarted it. I've
not stopped the clamav-daemon and clamav-freshclam. 

I believe I mentioned this earlier that as time gets close for the oom
the system will slow way down. For instance if I'm installing a new
application or doing an update or sometimes even opening nautilus the
system will 'freeze' the seconds on the clock will stop, the mouse will
stop being movable. Eventually it will unfreeze however at times 3+
minutes will have passed. Since I also have top running in another
desktop I'll see that the 1m load average will be up about 17+% though
I can't see anything in syslog causing this.
