Hello,
we have an P4/3GHz server running under netbsd 1.6 with 2 GB of RAM.
Since some days the "top" command gives the output below.
What is using the "1651MB File "of RAM?
Can anybody explain this?
Normaly on the server runs also an apache, mysql, qmail, etc. The "Free" memory goes to
under 10 MB Free.
I also give you the "ps -aux" output.
Thank you and best regards
R.M.Roppert
