TWS will periodically "hang" on Initializing managers after daily restart and have purple grid


 

This will happen rarely, but couple of times in last 2 weeks, the TWS was stuck on initializing managers very likely sometime after the Daily Restart. The grids will all be purple, and the only way out is to exit and restart. When I have checked the TWS log, I dont see anything obvious( no out of memory exception etc).I have the heap size at 2 GB. I can have a lot of orders at any time. so not sure if that can cause this. This is on Windows 10 offline build 978, Nov 13 2020

This affects my trading bot which is scheduled to run every day when market opens ( esp. on days when I am out of the house). Can anyone suggest anything to look for? Thanks
