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?

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, Krzysztof Ol
