      Hello,

      After running the server for a couple hours i start to get reports of “Freed object class: Unknown” with FastMM5.

      FastMM5 Debug Log: https://www.creationpower.gr/EventLog.txt

      Any ideas ?

      Thank you

      I can see two of them are related to ElevateDB indexes being freed. kbmMW as such do not do anything with EDB indexes, however what I notice is that you have several debugging layers enabled, MadExcept (which seems to trigger first in all cases), kbmMW’s memory debugging and finally FastMM5’s tracker.

      I wonder if MadExcept is “doing something”?

        Hello,
        I disabled kbmdebugmemory and madexcept so the new log is pure FastMM5:

          Thanks.

          It looks like that the transport is not disconnected before application shutdown. Can you add a transport.DontListen call and see if the errors disappears?

          best regards

            Hello,
            The server isn’t shutting down when the error occurs!
            It usually does this when the user is loggin/out.

            Thank you

        Hi,

        Im not aware about any reuse of freed objects in kbmMW. There can be issues on shutdown, if things are not closed in an orderly fashion, but that is not the case you are seeing.

        I have many apps that are running 24×7 using kbmMW messaging that do not exhibit any instabillity issues.

        I will however, get a license for FastMM5 and check it out more closely.

        best regards

        Kim/C4D
