Neil,

Thanks.~10-12GB of total RAM (16GB) are

How can Proc virtual memory parameters like inactive_clean_percent, overcommit_memory, overcommit_ratio and page_cache help me to solve / reduce Out Of Memory conditions on servers with 16GB RAM and lots of GB swap?

Kernel does not free cached memory (~10-12GB of total RAM - 16GB). Is there some way to force the kernel to free cached memory?

/proc/meminfo:

total: used: free: shared: buffers: cached:
Mem: 16603488256 16523333632 80154624 0 70651904 13194563584
Swap: 17174257664 11771904 17162485760
MemTotal: 16214344 kB
MemFree: 78276 kB
Buffers: 68996 kB
Cached: 12874808 kB

Thanks to all.

Marcio.
