With six gigs of memory, it looks like the VM has gone nuts trying to locate some reclaimable lowmem.
Suggest you send the contents of /proc/meminfo and /proc/slabinfo, captured during a period of misbehaviour.
Then please apply http://www.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.20aa1.bz2 and send a report on the outcome. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
