I've faced with the following problem: sometimes twslink stuck in
endless loop of messages "Can't find order with id=..." (order event
# 135). This order id is changed from time to time, but I never used
this order id. Could you help me with it?

Here the repeated part of TWS log file (all file is about 250 mb):
