while not all resource locks obtained { // in case of T3, they are A and B try to lock on resource; // immediate return success or fail if fail, release all unsecured locks; // in case of T3, C is secured, // so only A and B may be released, // in case of T4, both B ...
OK, I committed a complete fix. Am still not 100% happy with it but it's OK for merging. This fix removes the need for a TP thread when closing a connection, and when the opening attempt being released is synchronous. It should clear up this deadlock. There's a CI nuget available ...

If you have a thousand clients connected and reading from a table, and one locks that table, the other 999 will sit and wait as long as it takes for the lock to be released. This is minor compared to the danger of deadlocks, however, which is where one program has a lock on table...
Once the number of the device-busy responses counted by the counter unit M4 becomes a predetermined number, the expropriation unit M5 seizes the control of the logical storage unit when it is released. Thus, the expropriation unit M5 can prevent other transfer units from getting the exclusive us...
Deadlock clauses can further complicate matters where one party may argue that in fact commercial relations have broken down giving rise to a deadlock, and not just an exit situation, and therefore the provisions of the agreement dealing with deadlock should first be applied. This will real...
(transaction 2 inserted it but has not committed). If transaction 2 locks this record, then shouldn't transaction 1 just wait until the lock is released? I don't understand where the deadlock is coming from. Why having a unique index is not a good idea? The index ensures consistency of...
In this scenario, deadlocks may occur on the query notification system tables (for example, a system table with a name that resembles sys.query_notification_xxxxxx). Additionally, the following deadlock graph is logged in the SQL Server error log file: ...
released all its locks, and the other transaction can now get all the locks it requested. Thus, when you re-run the transaction that was rolled back, it might have to wait for other transactions to complete, but typically the deadlock does not recur. If you encounter frequent deadlocks, ...
