I see it here too on 128m box when stress testing. I sent Rik the proggy I was using, so maybe he'll be able to reproduce it.
Datapoint: Here it's looping in refill_inactive_scan with numbers like.. active: 20531 inactive_dirty: 102 inactive_clean: 0 free: 351 ..and _seems_ to not be able to find any pages to deactivate. I see a grunch of age_page_down_nolock/deactivate_page_nolock activity, but active stays constant.
Box can only be saved by sysrq-e when this happens.
