Powerpc architecture, running GPFS. Sadly, I dont have any real details on the workload that actually generated the oom condition, so dont know what allocation was failing, etc. > I have a patch for this, but wasn't really pushing it hard because it's > pretty unlikely for x86 and standard filesystems to oom from here...
