Error description

  • Under rare circumstances, incorrect checking for a null pointer,
    in activity metrics termination can cause an instance crash.
    The trap file created will contain a stack similar to the
    following:
    
    0        sqlmTermActivityMetrics.fdpr.clone.18
    1        sqlrr_activity_exe_stop
    2        sqlrr_activity_exe_stop
    3        sqlrr_open (engn/sqr/sqlrr_req_sql.C)
    4        sqljs_ddm_opnqry
    5        sqljsParseRdbAccessed
    6        sqljsParse.fdpr.clone.287
    7        sqljsSqlam
    8        sqljsDriveRequests
    9        sqljsDrdaAsInnerDriver
    10       sqljsDrdaAsDriver
    11       sqeAgent::RunEDU
    12       sqzEDUObj::EDUDriver
    13       sqloEDUEntry
    
    The database configuration parameter MON_ACT_METRICS
    would have to be set to NONE for it to be possible to
    encounter this trap.
