Hi
I am running AIX 5.2. My server is running low on memory. It it using about 1307775 file pages on a total of 1511424 (from vmstat -v).
I looked at the memory yesterday morning, and we had plenty of free memory. I did a backup from Windows (ftp mget command) of a large file selection. From this moment, free memory dropped to very low.
Question #1 : how do I prevent that to happen?
Question #2 : how do I "flush" memory for it to be normal, without restarting my server?
Here is the result of vmstat -v :
vmstat -v
