EMS probe leaking memory and crashing affecting UIM portal

Here is a cut from the log where the EMS probe is trying to invoke the servicenow gateway that we do not use and have not installed.

So I assume that some person has clicked the create incident button in the alarm console that then causes EMS to try to process the alarm

How can I clear these records out of the EMS probe to return it to normal processing?

there are 2 messages that EMS is logging over and over and over.

it eventually runs out of memory and crashes that unfortunately also breaks the UIM portal
