MySQL Error 3132: Locking Service Deadlock
Description
This error indicates that two or more transactions are stuck in a cycle, each waiting for a lock held by the other, specifically within MySQL's internal locking service. It typically occurs in highly concurrent environments when acquiring system-level locks, preventing further progress.
Error Message
Deadlock found when trying to get locking service lock; try releasing locks and restarting lock acquisition.
Known Causes
3 known causesConcurrent Resource Contention
Multiple transactions simultaneously attempt to acquire the same internal MySQL locking service resource, leading to a circular dependency where each waits for the other.
Application Logic Deadlock
The application's transaction design or sequence of operations creates a situation where locks are requested in conflicting orders by different concurrent processes.
Long-Running Transactions
Transactions that hold locks for extended periods increase the window of opportunity for other transactions to request conflicting locks, raising the risk of deadlocks.
