[squid-users] Major Problem with Restarted Squid Stable 2.6_19

I have several FreeBSD servers with 3 disks just for cache spools running
Stable_2.6.19 in accelerator mode.

 Every so often, I have had a server lock up on me. Usually, before I upgraded
them to ver 19, I would just reboot them and they would recover and start
working again. Now however, apon reboot, all the cache spools show lots of disk
activity at the same time, even when there is little to no traffic being sent
to the unit and requesting a file via the squid server is painfully slow.

 As you can see the cpu usage is very high. It takes almost 5 seconds for the
report to even show up. This is after the disks swap.state files are checked one
by one.

 The only solution I have been able to find so far is to destroy all the data
and have it rebuild it all.

 Any auggestions woudl be greatly appreciatted.

  Thanks
