Hello,
Yes, the NoSQL license (General license not the Enterprise license) would be required to eliminate the restarts. In the ma.log file, when Mango starts, it mentions that it is running NoSQL in free mode and that it will restart in 8 hours. The documentation to convert an H2 database to MySQL is found here: Database Conversions. If you need further assistance, please let us know. Thanks!
