A MySQL client's transaction fails with an error message:
Possible changes that could trigger this error:
- Slow write queries (due to inefficient SQL, data size getting much bigger, or other reasons)
- Decreasing the innodb_lock_wait_timeout variable size.
- Slow queries.
- Slow transactions with many faster queries, so that locks remain held for a long time.
