An unprovoked shutdown occurs during Spring boot executable jar execution.

Hello.

Currently, about 5 web projects written in spring boot on Linux have been distributed in the form of executable jar and are registered and running in service.

Occasionally, some projects are experiencing unprovoked shutdowns.

The log shows the same as when a normal shutdown command occurs.

Is there anyone who has experienced this phenomenon or who knows anything else to look at other than the spring log?
