ulNumOfActiveSlaves in NETX_MASTER_STATUS is sometimes not incremented after IO connection was successfully established

Sometimes it happens that the ulNumOfActiveSlaves field (located in  NETX_MASTER_STATUS) is not incremented although an IO connection to a target was successfully established and runs with no errors.
