Hi all,

I turned kernel debuging on and tried the key combinations when the machine was stuck
but it did not really help because the machine was not responding to this.

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

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
