The two processes that are involved in this deadlock both are supposed to first lock the row (in a transaction) and then each has to do a separate task of updating the row. No delete or insert statements are involved. My investigation shows me that the following happens, but I am at ...
That can help you to tune your application to avoid deadlocks. If frequent deadlock warnings cause concern, collect more extensive debugging information by enabling the innodb_print_all_deadlocks variable. Information about each deadlock, not just the latest one, is recorded in the MySQL error ...
Adeadlockin MySQL happens when two or more transactions mutually hold and request for locks, creating a cycle of dependencies. In a transaction system, deadlocks are a fact of life and not completely avoidable. InnoDB automatically detects transaction deadlocks, rollbacks a transaction immediately an...

If you are on RDS and your MySQL is having bunch of Sleep threads and you don’t know which connection is causing metadata lock, then you have to kill all the Sleep queries which are in mysql for more than a certain time. As we know “kill thread_id” is not permitted in RDS, but...
