Similar to me: o i386/7-STABLE server, o ia64/8-CURRENT client (which at the time of 7-release was therefore running 7-release). o I switched from UDP to TCP when TCP became default. I guess if UDP vs TCP is the problem, then it must be fixed already because I don't see the misalignment panics. I just don't know when it was fixed... -- Marcel Moolenaar xcllnt@mac.com
