The OOM Killer is working properly again in 2.6.10-rc2-mm4. Could you
try that kernel and report whether it fixed your problems too?
I had to turn off HIGHMEM support (see other response) but I mangaged to
My testcase forks a single child, then both parent and child proceed to allocate
and write to 3/5 of total system memory. Swap is disabled. There is barely
anything else running, so only one hog should have to be killed.
With 2.6.10-rc2-mm4, I got the following results:
running as root:
both memory hogs as well as the xterm in which they were started were killed.
In the process, the system was frozen for 14 seconds.
trial 2: both memory hogs killed, system frozen for 9 seconds
trial 3: both memory hogs as well as the xterm in which they were started were
killed., system was frozen for 15 seconds.
running as regular user:
one hog killed, system hung for 8 seconds
both hogs killed, timing window killed, system hung for at least 15 seconds
Doesn't look like the oom killer is entirely fixed.
