Jboss EAP 7.4.1 configuration issues

Question

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?
