I am trying to bring one of the environments EAP 7.0 to EAP7.4.1 and I have managed to migrate one of the environments successfully. However, on one of the environments, as soon as I start EAP after upgrade in the domain mode, the server runs out of memory with the error below:
> "WFLYCTL0030: No resource definition is registered for address [
> ("host" => "somehost-server-1"),
> ("server" => "server-1"),
> ("core-service" => "platform-mbean"),
> ("type" => "operating-system") ]"
I have tried to copy the exact configuration as the other environment where EAP is running smoothly and find no difference. I couldn’t find any help if I try to find this error, all I can see is that it has something to do with the Monitoring service of Jboss EAP. Can someone help?

I found the issue, apparently jberet was internally trying to fetch details about the job executions from the table(JDBC repository). And since there was a lot of rows in that table, the committed heap size would run out.
After I deleted rows from that table, the server looks stable and everything runs smoothly. I wonder how the server handles a large load since it is constantly trying to fetch that data. Is there an alternate to the solution?
