Insufficient data:

* Check you WCCP TCAM table size.

* Check your iptables/netfilter memory usage and table capacities.

* Check your available TCP ports.

* Check your Squid machines per-process FD limitations. As viewed by the 
OS and what Squid thinks are available.

* Check for forwarding loops (set 'via on' in squid.conf).

* Check your logs for any issues that may be reported. Especially squid 
cache.log and OS system log.
