MySQL Error 3133: Service Lock Wait Timeout
Description
This error indicates that an internal MySQL service or operation attempted to acquire a necessary lock but failed to do so within the specified timeout period. It commonly points to contention for internal resources or a service being blocked by another long-running process.
Error Message
Service lock wait timeout exceeded.
Known Causes
4 known causesHigh Internal Resource Contention
Multiple internal MySQL operations or sessions are simultaneously vying for the same critical resources, leading to delays in acquiring necessary locks.
Long-Running Transactions/Operations
An existing long-running transaction or internal service operation is holding a required lock for an extended duration, preventing other services from proceeding.
Insufficient Timeout Configuration
The configured `service_lock_wait_timeout` or similar internal timeout parameter might be set too low for the typical workload or expected internal delays.
System Resource Exhaustion
Underlying server resource limitations (e.g., CPU, memory, I/O) can slow down MySQL's internal processes, causing lock acquisition to exceed the timeout.
