no, not auto-shutoff. I have IBController to handle the shutdown timer. It just closed for some unknown reason. I am still trying to go through my logs and figure out what happened.
edit: I guess it was auto-shutoff after all. Looks like IBController did not do its job for some reason. !@##@#!@ when will IB take out this silly midnight server reset and TWS auto-shutoff. #$*&@#!&*$
