The kernel produces oops, randomly. It may happen any time after bootor in two-three days.

The traces are always same on any process making kernel emit oops.After free_pages, <sock_create>, <__up_wakeup> die on<kmem_find_general_cachep>. Either way, at the very end kernel freezeswith panic trying to kill init.
<kmem_find_general_cachep> <======
It is the slab.c in (/usr/src/)linux/mm/slab.c. Kernel is stablecustom compile from kernel.org versioned 2.4.30 with patches applied.
As I have searched for answer or possible solution, either the memorymanagement routines cause incorrect cache size returns after<free_pages> to cache stack or.. I do not know what. Anyways,
Please Help!
