Hi, In the same context I want to know whether kernel 2.6.13 broken? I got oom, and as per the documentation and code of out_of_memory, all the processes, which share the same memory address as the process chosen to be killed, i.e. threads, will be killed. But in my case its not the case always. At times the process chosen, "Angelia", is killed will all its threads but at other times, only some of the threads get killed and the print from oom killer (function out_of_memory) comes repeatedly but no process is killed. Why its so? Anticipation and regards, Abu. ---------------------------------------------------------------------------- ---------------------------------------------------------------- oom-killer: gfp_mask=0x201d0, order=0 Mem-info: DMA per-cpu: cpu 0 hot: low 2, high 6, batch 1 used:2 cpu 0 cold: low 0, high 2, batch 1 used:1 Normal per-cpu: empty HighMem per-cpu: empty Free pages: 712kB (0kB HighMem) Active:1359 inactive:122 dirty:0 writeback:0 unstable:0 free:178 slab:469 mapped:1244 pagetables:452 DMA free:712kB min:512kB low:640kB high:768kB active:5436kB inactive:488kB present:16384kB pages_scanned:5261 all_unreclaimable?
