Complete lockups while nightly cronjob

[Alexander Feigl <moondream@xxxxxxxxxxxx>]

Hi!

>From time to time I get complete lockups during the nightly cron jobs at 
04:00. As the machine is in X most of the time I was unable to record any 
OOPS data yet. As far as I remember I saw a "bug in slab" once I was in 
console. Is there an other way to record OOPS or do I have do write down the 
oops? (saving to hd would be great).

Using kernel-2.4.9 with development patches

gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release / Mandrake Linux 
8.1)
