Comment 1 Christoph Lameter 2007-11-14 14:03:33 UTC
This is a typical trace if slab memory objects were corrupted. Is this occurring
on a single machine or can it be reproduced on other machines?

This occurred only once on a single machine. However, with no reports from 
ECC, EDAC MC and MCE it is IMHO very unlikely for this crash to be caused 
by a hardware malfunction.

Memory can also be corrupted by faulty system software components 
overwriting memory. Recompile the kernel with CONFIG_SLAB_DEBUG on to 
have a better chance to detect these things.

If I only could do this... CONFIG_SLAB_DEBUG unfortunately makes my system 
so slow that it is not able to handle his normal tasks. Previously it took 
~2 months for this error to come out, it is not possible to leave it with 
this option enabled for so long. :(

Best regards,
