Correct LinuxNode Configuration?

This is a followup to my last, reference LOCKUPS IN SUSE 9.1. I was thinking about my LinuxNode configuration. I have gone into runlevel editor and have pointed incoming telnet connections to /usr/sbin/node. This seems to be working as-is. I did not change anything else in the telnet configuration. I am wondering if there are things in that configuration that I should change, things that if not changed, may be causing LinuxNode to lock up? This is a devistating problem because the computer requires power off and reboot in order to get it operational again. I am hoping that someone will recognize the symptoms of this problem and will be able to get me pointed in the right direction. Thanks for your time. 73, Gary, W7NTF
