Greetings,
I have a weird problem with a couple of Dual Redhat 7.2 machines; Both of them started
to show (not sure since when) a high usage number but the CPU or the IO looks to be
normal.
Here is the output of my w command and my /proc/loadavg:
[root@lnxdb0001 proc]# w
11:11am up 8 days, 21:37, 1 user, load average: 4.00, 4.00, 3.95
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
root pts/0 firewall.dev01.n 10:19am 0.00s 0.18s 0.01s w
[root@lnxdb0001 proc]# cat /proc/loadavg
4.00 4.00 3.95 1/62 4828
[root@lnxdb0001 proc]#
But the ps -ef or top doesn't show anything rare:
11:12am up 8 days, 21:38, 1 user, load average: 4.00, 4.00, 3.95
62 processes: 61 sleeping, 1 running, 0 zombie, 0 stopped

here is my uname:
[root@lnxdb0001 proc]# uname -a
Linux lnxdb0001 2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown
Doesn't look like a memory problem (in fact the box is not using swap at all):
[root@lnxdb0001 proc]# free
total used free shared buffers cached
Mem: 1028432 1022520 5912 159284 10764 760712
-/+ buffers/cache: 251044 777388
Swap: 131504 0 131504
Has anyone has faces this weird behaivour? There is way i can check who is causing
this problem (looks like a false alarm).
