I have an instance of WSO2 APIM version 4.2.0 installed on an Oracle Linux 8 server which has 16gb of ram. The problem noticed is that the more time passes, the more the consumption of physical memory increases even if no request is sent to wso2 APIM. This behavior manages to consume all the available memory to the point of making wso2 APIM unavailable and even the server on which it is installed.
