[cobalt-users] Raq2: What does kerneld do for me?

["JP Crametz" <jp@xxxxxxxxxxx>]

Hi:

I have to Raq2, in the office, one running smoothly, never crashing, the
other one, systemtically crashing every day or 2. The machines are
pretty much identical, apart from one being a nameserver, the other one
being a mail server.

At first glance, a  'ps ax' returns the following differences: The
machine that fails has a /sbin/kerneld process running,  Is this normal?
Or should I be looking elsewhere? I can't even get an idea of what
process causes the system to freeze.
Also, the machine that fails has this other process running
/sbin/mgetty -b modem, even though, there is no modem attached or
configured anywhere..

Any help welcome at this pont. I can't figure it out..

Thx,

JP Crametz
