I am finding if I manually restart the server after the daily reset times(a few minutes during the 0445 -0545 window - UK time), Gateway is pretty stable. However if I let it run overnight, the reconnect does NOT always survive the resets (1100 errorcode is not always followed by 1102) and I am building a try/except script to handle the error and restart Gateway using IB Controller.
I guess from your response, GAT, you have not experienced any disconnection issues in your live trading, which is interesting. Just speculating, could it be because you use cronjobs to restart the Gateway prior to commencing your daily trading sessions, and this occurs well after the reset time?
