Strange memory consumption
Hi,
I'm experiencing a very strange phenomenon on a RH4.1 system.
No heavy processes are running, yet memory consumption is soaring, and the
load is above 6.
In the process table, there's no process consuming a lot of memory, and
the sum of memory chunks used by processes is tiny compared to the total
memory use reported. Here's what 'top' output looks like (sorted by mem
usage):

Any idea regarding what's going on here will be appreciated.
