I'm having the same problem on a SLES10SP2,OES2SP1 host. We tried setting the first_watchdog_packet to 5. This reduced but did not eliminate the problem. Now I am getting users complaining again.
We originally found no answer on Novell's site. Instead credit goes to:
» NCP connections and Watchdog under OES Linux
Please let us know what Novell tells you.
Thanks,
Rob
