I use FreeBSD 8.2 AMD 64 with 4 GB of RAM , when I type

top

I see this

Mem: 25M Active, 3266M Inact, 518M Wired, 97M Cache, 418M Buf, 23M Free

only 22M of Ram is free ,
but when I reboot system , I see Have a lot of free RAM
Is this normal or my system has problem
I use this system for SAMBA and internet sharing with PF . and I do not have another service

A potential answer seems to be in a thread you started: http://forums.freebsd.org/showthread.php?t=26976.

Check your memory usage. There is a problem with 8.2-Release when used together with Samba, memory will just disappear. The fix is to upgrade to 8-Stable

Search the forums for "free memory is wasted memory". This comes up a lot.

So it's really using half a GB (Active + Wired) and most of the rest is being used as temporary storage and/or will be used/reused at some future time.
Unless it's moving hundreds of MBs in and out of swap space all the time, I'd say everything is perfectly normal.
