Hiya guys,


I'm getting the msg "hangcheck: hangcheck value past margin!" every few
minutes in the logs. It started all of a sudden. The kernel is a vanilla
2.6.14.5 on a remote box.

What could this mean ?

Thanks

it means you enabled the hangcheck timer watchdog, and it seems to think
the kernel is too busy or losing time ;)
Did you mean to enable that watchdog?

Yes, it's indeed enabled, i just remembered when you mentioned the word
"timer" hehe

But the system is not processing a heavy load. Here is a capture with top:
