exiting to shell leads to fader wing not responding

I needed to get some information from the shell on my console in the middle of the day (console name). I was under the impression that if I exited to the shell and did not make any change that the DMX output would continue. When I restarted the Console the leds on the fader wing started to blink intermittently and the fader wing stopped responding in a timely manner.  I would move sub faders and the LEDs would blink and the submaster would not respond or it would lag or even freeze.

I'll try a reboot when I get a chance and a copy of the log files but...

thanks
