ncpmount annoying kerneld?

Post by Jim Diamo » Wed, 05 Nov 1997 04:00:00



Hi,

On a 2.0.30 system, I am using ipx_configure and ncpmount to access
files on a local Novell system.  Recently I started process accounting
running on my system, and I noticed that I was getting a lot of
entries in the accounting log like:

  Userid Group  TTY  Command          Utime Stime Runtime Exit Proc start time
    root  root   ?   kerneld           0.00  0.00    0:00  126 14:33:10
    root  root   ?   sh                0.01  0.00    0:00  126 14:33:10
    root  root   ?   kerneld           0.00  0.00    0:00  126 14:33:08
    root  root   ?   sh                0.01  0.00    0:00  126 14:33:08
    root  root   ?   kerneld           0.00  0.00    0:01  126 14:33:05
    root  root   ?   sh                0.02  0.00    0:00  126 14:33:06
    root  root   ?   kerneld           0.00  0.01    0:00  126 14:33:04
    root  root   ?   sh                0.01  0.00    0:00  126 14:33:04
    root  root   ?   kerneld           0.00  0.00    0:00  126 14:33:02
    root  root   ?   sh                0.01  0.01    0:00  126 14:33:02
    root  root   ?   kerneld           0.00  0.00    0:01  126 14:32:59
    root  root   ?   sh                0.02  0.00    0:00  126 14:33:00

I had been running a kernel configured with IPX as a module, so I
re-compiled the kernel to have IPX built in, but I still get the same
sequence of kerneld/sh processes exiting every two (or so) seconds.
However, if I ncpumount the Novell file system, these message stop.

I've browsed some documentation, but I can't find anything out about
this.  (Yeah, I probably missed the correct doc, but...)

Can anyone tell me why all these kerneld/sh processes are happening?
Any way to prevent it (other than unmounting the Novell files)?

Thanks.

We faced the same problem about a year ago and I believe it is not solved
yet:
We are working within a net of about 200 Novell users. We detected that
the Novell message service sends each message to each user on our Linux
box; the kerneld starts a process for each incoming novell message, that
is, about 200 processes per sent message.
We 'solved' the problem by disabling the kerneld and executing 'nwmsg'
via the cron to receive novell messages.

Look at 'man nwmsg' and 'man kerneld'.

Try running kerneld with the debug option ('kerneld debug').

ncpfs appears to be built with a hardcoded path '/sbin/nwmsg' which
gets passed to kerneld upon receipt of a netware message.  Kerneld
launches (or tries to launch) /sbin/nwmsg.

I was noticing a lot of kerneld zombies until I created a link from
/sbin/nwmsg to /usr/sbin/nwmsg (where the ncputils default nwmsg).

ncpmount annoying kerneld?

I had a similar problem when I included IPX support in my
kernel.  I was getting a stream of log msgs that
it couldn't find a daemon that it was constantly trying to run.
The problem was solved by installing SAMBA

 
 
 

1. Q: kerneld: Ouch, kerneld timed out, messages failed.

I'm running kernel 1.3.79 and modules 1.3.69f.
The message below is shownd continuously:

kernel: Ouch, kerneld timed out, message failed

What would be the problem?

Perhaps the configuration file would be help. Thanks very much!
