One of our process model is being used inside a WEB API as startProcess, Some external System has hit the Web API 50k times & that particular process model & its sub processes has started 53k+ times. Due to this the Appian Server & the other process are not running . Monitoring tab is also not accessible. What is the easiest way to delete all this 50K instances so that the server can work properly

Can you clarify what you mean that "Monitoring tab is also not accessible" - do you not have security access? Is it timing out? Is it showing an error? If it's just timing out, you could try to create a process report that displays all of your processes: https://docs.appian.com/suite/help/latest/Configuring_Process_Reports.html
From there, you should be able to increase the page size to view / select all of the running instances and delete them.
Another question - did the processes complete successfully or did they error? If they completed, presumably they will eventually be archived based on your archival policy. You may also want to set your archive policy to be much shorter to prevent this in the future.
HI Peter, Monitoring tab was timing out & throwing error. All the Processes were active in a User input task node. Deletion from Process Report wasnt working as well, It was timing out as well. Due to huge server load maybe.
I followed the method mentioned by Vincenzo it worked. But anyway server is having issues since the mishap & team is working with Appian Support to make the server available
