Stop a Bot running with Queue

Hi, 

I am using Queue to manage the workload in my bot. The Bot was getting stuck Unexpectedly midway, while checking for a web control and not moving to the next step even after many hours(Until manually stopped by someone). Also I am unable to stop the bot from control room or even by logging to the Bot runner machine.

Please let me know if you have any solutions for the below issues.

1- Bot is stuck in-between and not moving to the next command or getting failed.

2- How to Stop a bot which is running with Queue

Thank you.
