So, I use to keep about ~50% mem utilization most of the time. Now its almost 100%, even after server reboot! It's a home server nothing taxing, samba, httpd2, webmin, squid, sshd, cups, dnsmasq.
System intel 750mhz 512M ram.(~ 17w CPU) opensuse 12.2
running top shows KiB Mem: 507788 total, 488744 used, 19044 free, 12988 buffers
And running thw following shows
#ps -eo pmem,pcpu,vsize,pid,cmd | sort -k 1 -nr

Like nothing is using it.
But the follow suggests 400M is sucked up as cached??

So what is eating all that cache? my squid isn't. Running a pmap -x on it shows under 16740K used for that. dnsmasq (my next assumption because of multiple giant host files that got 5x larger recently) pmap -x shows 7228K.
So how can I chase down what is going on, and what changed to eat up that ram?
Occasionally I'll run another service on that box(like wolfet for LAN), and also want to see about moving a 100m VM under it.
Where did my memory go?
