Hi,
I have a weird problem. My free -m output is:
root@mkslnx002:/proc/sys/vm# free -m total used free shared buffers cached Mem: 987 388 599 0 10 171 -/+ buffers/cache: 206 781 Swap: 1913 32 1881
This shows as much as 599 MB of free memory while the cache using only 171MB. Usually people have it the way round ;-)
Now, this is not normal for this server, it used use way more for cache, but now it doesn't. That forces the apps to fetch for iscsi storage more often than I'd like it to.
What might've happened to the OS that it's refusing to use more memory as cache? The server got slower and I'd like to be able to revert the situation without a reboot.
Please CC me, I'm not on the list.
Thanks! Maciej
