IB Live Error

Hi, 

It is my first time to live my algorithm, which runs normally during backtesting. However, it returns me a few errors when I lived it. Could you please help me on these issues?

 

Firstly,  I didn't see any error message before today marker opened, so I assume it runs normally? but it didn't place any orders at the set time.

Secondly, When I lived my algorithm, it only takes about 120+MB memory, it returns me an error of memory usage maxed out.
