I do think that I might have found the cause of the problem. I was running powerd and the cpufreq module was loaded each I had problems. I now turned powerd of and did not load the cpufreq module and the machine is now running for 23 days in a row. Does anybody know wether this is possible/makes sense ? kind regards Kris Kennaway schreef: > On Fri, Oct 27, 2006 at 09:35:09AM +0200, bram wrote: > >> Hi all, >> >> I'm rather new to freebsd so forgive me if I am saying things that don't >> make sense. >> >> I have a dual opteron server running freebsd 6.1/amd64 updated 4 weeks ago. >> >> Since I moved to 6 I've been having tho following problem. >> >> When I put heavy load on the server (python scripts that take 20 minutes >> to complete) the server sometimes hangs. >> >> I can then not ping it anymore and it does not respond to anything (no >> keyboard power button etc.). >> Mostly there are no error messages or anything so I have no clue to what >> the problem is. >> One time it did give an error but I did not wrote it down, but as I >> recall it was something like SMP spin lock timed out. >> >> It hangs every three weeks >> >> Please give me some info on how I can get it to give more info or how to >> resolve this problem. >> > > See the chapter on kernel debugging in the develpers handbook > > Kris >
