I have a problem in the cache notifications of integration directory. It will always have some error entries. When i click on "Repeat cache update for instance" button and then refresh, it will turn green.
I have checked my http destination "INTEGRATION_DIRECTORY_HMI". It is giving a return code of 500, but it has the status text as "Internal server Error".
Also at some times i keep on getting system messages in the ID like: "Unexpected error during message processing: javax.transaction.HeuristicMixedException: com.sap.engine.services.ts.exceptions.BaseHeuristicMixedException: One or more XAResources were not commited because of Exception in the second commit phase."
