What makes you think you have memory problems? Of the 5GB, just under
3.5GB is being used by the OS to speed up disk accesses (cached) and
another 200+MB is being held by the OS for quick allocation (buffers).
The 30MB of free memory is not being used at all, and as such is
effectively wasted. Since it's just over half a percent of your total
RAM, I suppose that can be forgiven. ;o)
please help me to put correct conf
Bump that high_memory_warning to half your RAM, or reset it to the
default value, which will disable it.
thank you

P.S. Have a gander at the RH9 admin primer page on memory usage
(http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/admin-primer/s1-memory-rhlspec.html).
The tools used haven't changed significantly in the intervening time.
