MariaDB Error 1704: Heartbeat Period Exceeds Timeout
Description
This error occurs in MariaDB replication when the configured `rpl_slave_heartbeat_period` (or `slave_heartbeat_period`) is set to a value greater than or equal to `slave_net_timeout`. It indicates an illogical configuration where the slave's network timeout will expire before it expects the next heartbeat from the master, potentially leading to unnecessary connection drops or replication issues.
Error Message
The requested value for the heartbeat period exceeds the value of slave_net_timeout seconds. A sensible value for the period should be less than the timeout.
Known Causes
3 known causesIncorrect Replication Parameter Values
The `rpl_slave_heartbeat_period` or `slave_heartbeat_period` variable has been explicitly set higher than or equal to the `slave_net_timeout` variable, creating a logical conflict in the replication setup.
Manual Configuration Mistake
An administrator manually adjusted replication timeout or heartbeat settings without ensuring the logical relationship between the two parameters was maintained, leading to the conflict.
Inconsistent Configuration Across Settings
The heartbeat period and network timeout values might be defined in different configuration contexts (e.g., global vs. session, or different configuration files) leading to an unexpected conflict when applied.
