Adrian,

Yep I've seen that and it's easy to reproduce by lowering the number
of authenticators. So when I start squid configured with:
auth_param ntlm children 50

# /usr/local/squid/sbin/squid -d100 -X -N -D -f /RamDisk/squid.conf
2008/02/19 14:29:09| WARNING: All ntlmauthenticator processes are busy.

# echo $?

It exits immediatly with return code 134
