If I understand the situation correctly (which I may not} in my system this happens: All real and virtual memory is allocated (The system has 16 Gb RAM + 32 Gb Swap.), but more memory is needed, at which point oomd starts killing processes. The system often becomes quite slow, with a lot of disk activity, before processes start to die. Cures might be more RAM, more swap, or cutting the system load. More swap is probably a bad idea, since the system already appears to be running slow on account of a lot of swapping. -- Sincerely Jonathan Ryshpan <jonr...@pacbell.net> Some people want something for nothing, however much it costs. -- David Ryshpan
