No effect from ^C whatsoever. Typed
epicsMutexShowAll 1 3 times to blank screen – no response From: Mark Rivers <rivers at cars.uchicago.edu> Can you type ^C to abort the casr command? It could be a deadlock. If that works then type epicsMutexShowAll 1 several times and see if the same mutexes are always locked. That is the symptom of a deadlock. Mark From: Tech-talk <tech-talk-bounces at aps.anl.gov>
