A server reload is required

Good Morning

We have a jboss environment which is runnig a few apps/jvms on.
It consists of 3 servers which is running eap 7.1
2 of those servers are running the apps

It keeps showing following,

"A server reload is required"

This is on the EAP management Console

After stop and starting the app it goes away but returns in a few days

Can anyone advice me please
