| Doc Text: |
Previously, when the rotate_relay_log() function was called, an unresolved concurrent access to a shared resource occurred. As a consequence, MySQL terminated unexpectedly with a segmentation fault. To fix this bug, a mutex lock on the resource is now used during the rotate_relay_log() call, and MySQL no longer crashes in this scenario.
