Amos, Odd enough the same config and same squid/OS build in another box worked without any problems. Something happened in that Dual Atom 1GB box that squid didnt like. Below is the output of cache.log on the fast machine FYI in case there is some kind of obscure bug. 2010/02/16 14:39:13| Starting Squid Cache version 3.1.0.16 for i686-pc-linux-gnu... 2010/02/16 14:39:13| Process ID 19843 2010/02/16 14:39:13| With 1024 file descriptors available 2010/02/16 14:39:13| Initializing IP Cache... 2010/02/16 14:39:13| DNS Socket created at [::], FD 5 2010/02/16 14:39:13| Adding domain my.domain from /etc/resolv.conf 2010/02/16 14:39:13| Adding nameserver 4.2.2.2 from /etc/resolv.conf 2010/02/16 14:39:13| Adding nameserver 4.2.2.1 from /etc/resolv.conf 2010/02/16 14:39:13| Adding nameserver 196.40.3.10 from /etc/resolv.conf 2010/02/16 14:39:13| Adding nameserver 196.40.3.13 from /etc/resolv.conf 2010/02/16 14:39:14| Unlinkd pipe opened on FD 10 2010/02/16 14:39:14| Store logging disabled 2010/02/16 14:39:14| Swap maxSize 0 + 262144 KB, estimated 20164 objects 2010/02/16 14:39:14| Target number of buckets: 1008 2010/02/16 14:39:14| Using 8192 Store buckets 2010/02/16 14:39:14| Max Mem size: 262144 KB 2010/02/16 14:39:14| Max Swap size: 0 KB 2010/02/16 14:39:14| Using Least Load store dir selection 2010/02/16 14:39:14| Set Current Directory to /usr/local/squid/var/cache 2010/02/16 14:39:14| Loaded Icons. 2010/02/16 14:39:14| Accepting HTTP connections at [::]:3128, FD 11. 2010/02/16 14:39:14| HTCP Disabled. 2010/02/16 14:39:14| Squid modules loaded: 0 2010/02/16 14:39:14| Ready to serve requests. 2010/02/16 14:39:15| storeLateRelease: released 0 objects 2010/02/16 14:39:43| Preparing for shutdown after 4 requests 2010/02/16 14:39:43| Waiting 0 seconds for active connections to finish 2010/02/16 14:39:43| FD 11 Closing HTTP connection 2010/02/16 14:39:45| Shutting down... 2010/02/16 14:39:45| basic/auth_basic.cc(97) done: Basic authentication Shutdown. 2010/02/16 14:39:45| Closing unlinkd pipe on FD 10 2010/02/16 14:39:45| storeDirWriteCleanLogs: Starting... 2010/02/16 14:39:45| Finished.
