    QUESTION:

    Message: Exception of type 'System.OutOfMemoryException' was thrown.
    Category: General
    Module: ExecuteQueryDirect
    Severity: Error
    DebugMessage:    at BMCSoftware.PASM.CDB.DBCore.SchemaBridge.GetQueryItemsString(String ItemName, String SQLSignature, Int32 iFirstRec, Int32 iNRecords, Int32 ItemLength, String Type)
       at BMCSoftware.PASM.CDB.DBCore.SchemaBridge.ExecuteQueryDirect(ExecuteQueryRequest request)


    ANSWER:

    This exception was caused due to insufficient available physical memory on the server.  In this instance only 4 Gig of physical memory was installed on the server.  The minimum recommended memory for a CDB installation is 8 Gig and 16 Gig would be better.  

    Once the memory was increased, in this case to 16 Gig, the graphs that were failing before produced the appropriate output.
