I just updated the Test Firewall we're using from 5.001 to 5.004 & have found that I can no longer surf through the HTTP Proxy. The Problem does appear to be started when the content filter is running, so far the only way I can get the traffic to run again is if I shut down the content filter & clear the cache or stop/start squid. I did notice in the self monitor log that weed is getting reset & exit's with a status of 0
if anyone needs a spitout of logs to verify/test it let me know what log spitouts you need & I'll post them.
