I have had a play around with the Overcommit_memory settings and Overcommit_ratio settings and i am still getting "Out of Memory - killed process" errors. One thing i did notice was the errors are appearing on our old supermicro machines only, we also have HP Dl360 machines that are working fine. I have compared the top command on both machines as per text below when the machines have just been rebooted and the output of the supermicro machines show "Swap 0K av". Does this mean that for some reason it is not allocating any swap space at all, if so how to change this to reflect the other Dl360 machines. Any help would be much appreciated.
