| Description |
|
Clean shutdown will close the WiredTiger connection which unconditionally closes all the sessions, including the one used for backup. Therefore, if WiredTiger::endBackup races with clean shutdown and tries to close the session that is already closed by clean shutdown, a segfault will happen. |
