What happened?

After the pod runs for a period of time, it will be killed. Through auditctl tracking, it is found that the container is killed by runc.

Through monitoring, it is found that all resource utilization is very low, requests and limits are within the range, and there is no OOM situation.

What did you expect to happen?

Reason for being killed

How can we reproduce it (as minimally and precisely as possible)?

Because it is sporadic, it is difficult to reproduce accurately

Anything else we need to know?

The probe used is execProbe
