Let me know if you need any more input.

After a while the kernel hangs, and after rebooting my /var/log/messages has this as the last output: May 29 15:10:06 bongani1 last message repeated 689 times May 29 15:10:06 bongani1 kernel: e:0x20 May 29 15:10:06 bongani1 kernel: lisa: page allocation failure. order:0, mode:0x20 I was running a couple of applications Mozilla-mail, KDE, Some Java Application Server ... When I load the a application, some memory is freed from the Slabs. The PC was just sitting there both times running those applications and both times I returned and found it hanging. cat /proc/slabinfo looks like this slabinfo - version: 2.0 (statistics) # name active_objs num_objs objsize objperslab pagesperslab #!
