Does this app. have > a bug? I've never had a problem with it, but I've never let it run for more than 5 minutes at a time while tracking down a problem station. And I've always quit it manually using CTRL+C or Q. Doing a quick test on a 6.0-p4 system, I can reproduce this issue, though: in terminal 1: ssh to remote system su - to root start trafshow in terminal 2: ssh to remote system su - to root kill -9 the first instance of csh check ps to make sure it's dead but trafshow is still alive check top and see 0% idle, ~66% system and ~33% user, with trafshow at the top of the process list kill trafshow in top, get 99% idle Not sure if this is a bug in csh, trafshow, both, or something else. ---- Freddie Cash fcash@ocis.net
