Hi! A while back I wrote about some problems I was having with FreeBSD cras= hing randomly. I then disappeared for a while, due to a variety of issues, = but I'm still having problems. The computer in question is a general-purpose server -- it runs listservs, = websites, databases (both MySQL and PostgreSQL), and Amanda to back up a fe= w other computers. None of this is high volume -- load averages are all les= s than 1. It has two Intel Xeon processors, with a total of 16 virtual cpus. It runs = FreeBSD 8.1, using the amd64 branch in order to access 12G of RAM. It has a= n Adaptec 5805 RAID card, and is using the Adaptec aac driver 2.2.9-17911 (= which is also the flashed BIOS version), and has one array, which is a RAID= 10 array. Note that I'm not using the aacu driver, but most of the crashes= happened when I was. Based on the randomness of the crashes, I suspect that it's a hardware prob= lem. I have tried to enable core dumps, but it has never succeeded in actua= lly writing one out -- it looks like it has a second crash when it tries to= save the core. This leads me to suspect that it might be a problem with th= e RAID card, but I'm not sure. Is there some way that I can use the information provided during the kernel= panics to determine where the problem is? I have photographs of almost all= of them. There are a few crashes that didn't result in kernel panics; inst= ead there were a few gibberish characters (from the >128 ASCII codes) on th= e screen. I have pictures of these as well.
