MySQL Error 4080: Concurrent Procedure Call Conflict
Description
This error indicates that a stored procedure was invoked while another call to the *same* procedure was already in progress. MySQL prevents concurrent execution of the same procedure to maintain data consistency and avoid race conditions, thus no action was taken on the new call. This typically occurs in highly concurrent environments or when an application rapidly retries a procedure call without waiting for the previous one to complete.
Error Message
The %s was called when there was already another concurrent call to this procedure. No action was taken. Wait for other calls to %s to finish before retrying.
Known Causes
3 known causesApplication Logic Conflict
An application might rapidly retry calling a stored procedure without proper synchronization mechanisms, leading to overlapping calls to the same procedure.
High Concurrency Environment
In systems with many concurrent users or processes, multiple sessions might attempt to execute the same procedure simultaneously before previous executions complete.
Long-Running Procedure
If a stored procedure takes a significant amount of time to complete, subsequent calls from other sessions or even the same session might overlap before the initial execution finishes.
