Hi,
thanks for your fast reply. I was doing this test code:


    [
    [
        top select: 'SELECT * FROM version()'.
    ] repeat
    ] ensure: [
        ObjectMemory compact.
        DBI.Statement allSubinstancesDo: [:each | each class printNl].
        DBI.ResultSet allSubinstancesDo: [:each | each class printNl].
    ].

then using CTRL+C and it appears that after GC many ResultSets are still in
the image. I am now going to use your trick to find the owners.

thanks
