MariaDB Error 1703: Invalid Heartbeat Period
Description
This error indicates that the configured replication heartbeat period on a MariaDB replica is set to an invalid value, specifically less than the minimum allowed 1 millisecond. When this occurs, the system automatically resets the heartbeat period to 0, effectively disabling the heartbeat mechanism for that replica connection. This can prevent the replica from accurately detecting master outages when there is no replication activity.
Error Message
The requested value for the heartbeat period is less than 1 millisecond. The value is reset to 0, meaning that heartbeating will effectively be disabled.
Known Causes
3 known causesMisconfiguration in `my.cnf`
The `master_heartbeat_period` (or equivalent) parameter in the MariaDB configuration file (`my.cnf` or `my.ini`) is set to an excessively small or invalid value (e.g., 0 or negative).
Incorrect `CHANGE MASTER TO` Statement
A `CHANGE MASTER TO` statement used to configure replication was executed with the `MASTER_HEARTBEAT_PERIOD` option set to a value less than 1 millisecond.
Automated Scripting Error
An automated script or provisioning tool attempted to set the replication heartbeat period to an invalid value during server setup or configuration update.
