For whatever reason, that happens when the system attempts to do the nightly backup and MySQL hangs. Everything checks out so I can only figure that there is some type of race condition but I haven't been able to identify it. I've even considered migrating to MariaDB to see if that would make a difference. The logs show nothing and the disk and DB check out. Why couldn't BOINC have used a real DBMS?
