After the update from StoRM v1.11.19 to StoRM v1.11.20 into a production host at T1, Backend's communication with MariaDB started failing with the following error:
Caused by: java.sql.SQLException: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
The first thing done to recover from this error has been downgrading to StoRM v1.11.19. All started working again.
We want to understand if an urgent fix to StoRM Backend is necessary or a workaround can be applied.
