You'll know OnCall is in Debug mode when a debug log window appears alongside the
main OnCall window.
Repeat the steps that caused the socket/connection error. Find the new file oncall.dbg
and send it to us at email@example.com.
Disable Debug mode by choosing Beginner or Novice from the same preferences screen.
