Have you been running that same setup already before your Apr > 1st, r206031, kernel? If so, from when was your last kernel? Yes, this configuration works on another server fine (8.0-STABLE FreeBSD = 8.0-STABLE #3 r205202) Made few more tests. All tests I make using psql command (as it is 100% = reproducible, may be now try spot it using telnet/netcat, without = involving pg). psql accomplish login operation fine, panic appears after = i run any command like \d, so I think it depends on packet size. Current picture is: 1. When connect from host machine - works fine. 2. When I connect from other server - works fine. 3. When connect from another jail on the same box as db's jail (tried = from few jails) - kernel fault.=20 Also tried security.jail.allow_raw_sockets on/off - nothing changes.=20
