[SunHELP] Free Memory

[DAUBIGNE Sebastien - BOR]

Be aware that Solaris 2.x will use every little available physical =
memory=20
for file-system cache. This space is freed up by the page scanner each=20
time free memory falls under "lotsfree" (or "cachefree" if priority =
paging
is
enabled on Solaris 2.6).

I would recommend you RMCmem package (available at sunfreeware.com),=20
which reports physical memory usage :=20

# prtmem
Total memory:           18122 Megabytes
Kernel Memory:            803 Megabytes
Application:             2813 Megabytes
Executable & libs:         56 Megabytes
File Cache:             12009 Megabytes
Free, file cache:         257 Megabytes
Free, free:              2188 Megabytes


Here we have 12 G used for file-system cache. Note that this space =
could be=20
given back to applications if they ask fo it.

	Hi all,

	I have a E420R server with 4G memory. when i check for the free
memory it=20
	always gives me a number which in no way matching the memory used by
all the=20
	processes running at that time. what I meant is that the memory
usage shown=20
	by the system is much more than that being used by the processes at
that=20
	time.

	if i reboot the server, it seems to be fine but after a couple of
days, i'm=20
	running into the same issue.

	Now the million $ question is "what happened to the rest of the
memory?"

	any help would be appreciated.


	Thanks,
	Mari
