We have just upgraded to the latest release of Squid 3. We have tried both the Squid Cache version 3.0-PRE3-20050608 and Squid Cache version 3.0-PRE3-20050609 with squid_rad_auth version 1.06 and squid_radius_auth 1.07. Each time we authenticate to our windows 2003 radius server, we receive the following message and squid crashes and restarts. 2005/06/09 17:09:21| assertion failed: AuthUserRequest.cc:757: "this != NULL" Are they any ideas as to why this is happening? Everything works using Squid Cache version 3.0-PRE3-20040219. We are using Fedora Core 1. Any assistance is welcome! Sam Reynolds
