WL - instances are getting shut down automatically

[KdM]

Hi Experts,

We are running ATG on Weblogic,
But recently we are seeing that some of the live prod instances are getting shut down automatically.
Nothing much in our logs,

Have you guys faced this kind of issue ??

Note :  in the Apache logs that indicate attempts from outside to shutdown the JVMs, -

Any thoughts highly appreciated,

Warm Regards
KdM
