Squid eating up all CPU

["Raymond A. Meijer" <rmeijer@internet.gr>]

Hi,

I have an interesting problem. I've been running Squid for a long time now on 
my workstation with its cache directories on a Reiser4 partition.

Since Reiser4 has been stable for some time now, I decided to reformat my 
other partitions (except / which is Ext3) to Reiser4 as well.

Everything seems to work well, except..the Squid process is eating up all CPU:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 4787 proxy     39   0 45700  10m 2580 R 87.7  1.4   7:12.94 squid

This happens even when there are no connections made through Squid!

My machine is a Pentium4 1.8GHz with 768MB RAM and 2 WD 40GB HDDs.

It's running Debian Testing with the following Squid (related) packages 
installed:

ii  squid                         2.5.6-8
ii  squid-cgi                     2.5.6-8
ii  squid-common                  2.5.6-8
ii  squid-prefetch                0.7-1
ii  squidclient                   2.5.6-8
ii  adzapper                      20040408-1

Kernel 2.6.8.1-cko5 is being used.

I though I'd ask this list since Squid was working fine, with low CPU usage, 
for many months. I've rebooted the machine several times in the past (before 
converting the system partitions to Reiser4) and Squid never displayed this 
behaviour before.

I don't see anything relevant in the Squid log files or in the syslog.

Where do I start the troubleshooting process? Has anybody seen this before?
I'm willing to try anything to pinpoint the problem and make sure it's not 
Reiser4 causing it ;)

Please let me know what other information you'd need.


Thanks,

Ray
