Hi, Victor, thank you for reporting this, the disconnection issue would not be caused by a cBot, you need to contact Spotware regarding this, if the connection is lost then cTrader will become unresponsive anyway.
The issue with high RAM and CPU we can look at if you provide your cbot parameter settings and list all the cBot instances you were running.
If you were to run a backtest or optimisation on this machine then you will see high memory and cpu usage like your are seeing now as cTrader will hold onto the memory and CPU, you need to restart the machine and then start all your cbots.
Please confirm that you aren't running any backtest or optimisation?
Please confirm that you are not running any other cBots or indicators?
Please confirm that you are having the same issue with the switchback on all your machines and it is not just this one?
Can you provide settings files for all cbot instances?
I will probably run the same setup on a clean server and monitor the RAM and CPU usage.
