I ran into the same issue today and the fix which helped me out was quick as pointed out in the log-file: "... you can set innodb_force_recovery > 0 in my.cnf" https://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html This will not generally fix the issue / bug, but it will make the DB accessible again: 1. I edited the file core\mysql\my.ini and added after [mysqld] : innodb_force_recovery = 1 2. Restarted the SQL-Server 3. Removed the formerly added line 4. Restarted the SQL-Server again So it was just a matter of seconds, everythings working fine again.
