Tackle possible hanging on Waiting for log copy thread to read lsn XXXXXXXXX #4
Description
In mariadb-operator/mariadb-operator#141 (comment) it was reported that mariadb-backup is known to sometimes hang on Waiting for log copy thread to read lsn XXXXXXXXX which requires master restart.
I have not yet faced such an issue myself, but if it indeed can happen, then perhaps there is a way to somehow tackle it.
