I spun my own as there were no precompiled versions when I started with 3.5.x. I'll look at your rpms and test those, but in a nutshell after putting a server in production I get the following errors, where squid seems to restart

FATAL: Received Segment Violation...dying.

This runs fine with a single proc box in a low volume environment. This does not seem to work in a multi core server in a very busy environment. I've read some things and it appears others have had issues and your suggestions and others was to try to run with -N, that doesn't seem to affect my issue and I get the FATAL's and core dumps still

I'lll try your rpms first

Thanks

Tory
