queryLockContentionStats(active: Boolean output;
startingProc: Process output;

startTime: TimeStamp output);
The queryLockContentionStats method of the System class retrieves information about the current recording of lock contentions.
A lock contention occurs when an attempt to lock a persistent object is queued or rejected because the object is already locked. For details about the information returned in the output parameters, see "
The recording of lock contentions is under the control of the process that initiated the recording; that is, only that process can stop or restart recording of lock contentions. Although any process can use the queryLockContentionStats method, it should be assume that recording can stop or restart at any time, if it is not the process that started the recording.
