(3 or 4 I think), I often find my machine with my X session killed in the morning, and the kdm login screen displayed. This morning, I decided to save the /var/log/messages to check it before rebooting, and saw that the OOM killer triggered during the night. So, I quickly made a copy of it, and a slabtop output. There came the surprise : OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 12899448 12899445 99% 0.11K 358318 36 1433272K task_delay_info On a freshly booted machine, the same entry shows : 3204 3191 99% 0.11K 89 36 356K task_delay_info after the X session is started. Please find attached the slabtop -o output.
