Description:
Bug ID 777389: In rare occurrences related to PostgreSQL monitor, the mcpd process restarts ... Last Modified: Apr 26, 2024 ... Impact ... Failing to receive a monitoring response from the SQL server, MCPD goes into an infinite loop and skips the heartbeat report, resulting in its restart. ... While MCPD is restarting, the system is offline and does not process traffic. ... After restart, system operation returns to normal. ... Conditions ... -- The 'mcpd' process attempts to read monitoring data from the PostgreSQL server, but no data is available. -- A contributing factor might be that the AFM module is licensed but not configured. ... Workaround ... The chance of occurrence can be minimized by making sure that control-plane processes have sufficient memory to run efficiently. ... Fix Information
