 Description  « Hide
Circle in wait-for graph will be broken automatically if at least one node waiting with timeout.
Lock manager may wrongly report such circle as deadlock and chosen victim may be not ready to handle such error.
This may lead to "lock conversion denied" and "lock denied" bugchecks in CCH.
