[squid-users] Help: SQUID 2.4STABLE2 uses 50-100% CPU every 5-10 sec.

Hi,

I am using SQUID 2.4STABLE2 on a Linux 2.4.5 machine and I noticed that
every 5-10 sec. the CPU spikes to 50-100% for about 2 sec. then comes back
to normal, only to reach 100% again 10 sec later.

The cache has no load at all, i.e. nobody is sending requests, it is just
sitting there "idle". I don't think these CPU usage spikes are normal.

I tried both ufs and aufs and they both have the same problem. I was not
able to start it with the storage type 'null' even though I compiled it
with '--enable-storeio=aufs,null,ufs'

ICP and WCCP are turned off. The configuration is very basic.

I ran an strace on the process to see what it's doing, but I can't make
any sense of it:

*repeated a lot*
poll([{fd=10, events=POLLIN}], 1, 0) = 0

*shows up once in a while, possibly corresponding to the CPU spikes??*
poll(0xbfffcc10, 0, 0
) = 0

Has anybody noticed this behavior? Any solutions?

Thanks.
