Squid simply restart it thread. Delegate fails off completly. Here is the network configuration: --<cut here>-- dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 195.209.225.34 netmask 0xfffffff0 broadcast 195.209.225.47 inet6 fe80::280:48ff:fefb:1fd6%dc0 prefixlen 64 scopeid 0x1 ether 00:80:48:fb:1f:d6 media: autoselect (10baseT/UTP) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP none xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.56.1 netmask 0xffffff00 broadcast 192.168.56.255 inet6 fe80::260:8ff:fe2f:db2f%xl0 prefixlen 64 scopeid 0x2 ether 00:60:08:2f:db:2f media: autoselect (100baseTX <full-duplex>) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> --<end cut>-- All routes are static. Any net application running from box (ftp, lynx) is going ok. I can nslookup FQDN, trace to destination etc. Squid versions tested: 2.4STABLE1, 2.3STABLE4 Delegate versions tested: 6.1.21 >How-To-Repeat: Install clean FreeBSD (burned from ISO). Setup network. Install squid or delegate. Configure proxies. Request data from local to global nets. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
