Subject: severe slowdown with 2.4 series w/heavy disk access
Date: Wed, 26 Dec 2001 00:17:16 -0500 [thread overview]
Message-ID: <3C295D5C.50EE365D@home.com> (raw)
I have been having this problem with the whole 2.4 kernel series.. Under
heavy disk access, the entire system will slow down and almost all of my
memory, save 5 megs, gets used up, never to return. I am currently
running 2.4.17 on a machine with 416 megs of ram, Duron 750, not
overclocked. Cpu temp does not exceed 107 deg F ever, so I don't think
its a heat issue. I have an MSI K7T Pro2 motherboard, using the KT133
chipset. Anyway, the following is how I can duplicate the problem, in
about 5 minutes. I only used mozilla for this because I was working
with it when I decided to isolate the problem. Also note this happens
more than just with tar, and sometimes it happens for no apparent reason
at all.
*** free and ps -ax, before the slowdown:
