Final incarnation can be picked up at http://marc.theaimsgroup.com/?l=linux-kernel&m=110269783227867&w=2 But on my machine it doesn't address the issue you speak of. When I run something as demanding as that (end of memory, eating a large chunk of swap) it behaves like yours. Gkrellm stops - no screen updates, mouse becomes very unresponsive etc. Though I saw that as "normal" for the workload. In this appartment there's no difference between 2.6.9 patched with the kswapd fix and the oomkill patch, or 2.6.10-rc3 with or without oomkill patch. Can't comment on 2.6.8 since I didn't exhaust memory with applications back then. Mvh Mats Johannesson
