I originally installed FreeBSD 9.2 Release/amd64 but kept having kernel panics after varying amounts of uptime and while running the following command against some or all of the SATA hard drives in the system: dd if=/dev/zero of=/dev/ada/n/ bs=100m & A sample vmcore file is here: http://codepad.org/FIjqh2Nt While canvassing the FreeBSD Forums I followed a suggestion to try 10.0 RC4/amd64. The machine still panicked under the same conditions at around 27 hours uptime. The vmcore file is here: http://codepad.org/svtRfRT1 System memory has run Memtest for 62 hours and 47 passes without error and the chassis has dual 740W PSU's so I think I have memory and PSU possibilities eliminated. Apologies if I've sent my plea to the wrong place. Tell me where to go and I'll bother someone else. Thanks, Dan. -- The only person who always got his work done by Friday was Robinson Crusoe.
