Hello,
I have a process which eats all the memory available (buy making a loop of mallocs, writing and reading the malloc'd memory) called memoryEater (to torture test the memory system before going to a production system)
My kernel is 2.4.2smp on a 4 way Alpha machine with 8 Go of RAM.
When the process is launched under a user ID everything works the way it should, i.e. the malloc works fine until the process eats 7.8 Gbytes of RAM and then the process stops on a segfault.
When the process is launched under the root ID, I see the OOM in the /var/log/messages saying it wants to kill this process (memoryEater) but it does not kill it.
Hitting Control+C, kill PID -9 does not work. Halting the machine is my only solution.
Any ideas ?
