daemons/blockchain : Mysql2::Error: This connection is still waiting for a result, try again once you have the result: ROLLBACK

[alextegro]

Hello Openware team
I have an issue with RDS connection during blockchain deamon run:

Mysql2::Error: This connection is still waiting for a result, try again once you have the result: ROLLBACK

This sounds as race condition from known issue on mysql2 lib
brianmario/mysql2#1274

Can you please help to figure out solution?
