Re: CPU usage jumps to 100%?

This is not a known problem.

Debugging with gdb should be possible, like for any other program.
Either attach gdb to the Squid process, or start Squid from gdb and wait
until the error occurs.

If your Squid is multithreaded (async-io enabled) then your gdb binary
must support threads, or things will get quite confusing.
