Olaf.. yes I had a problem with a dameon, I think it was
bdflush, but cannot remember. I just SIGTERM'd it. It did not
crash my system or hang, it, 2.2.9 has been VERY stable for me.
I have had a process or two suddenly grab a cpu and slam it 99%
and keep it there till I SIGTERM the program, but that has been
rare (less than 5 times).
