Opened: Nov 29, 2021 Severity: 2-Critical
If debug logging is enabled for a database monitor (mssql, mysql, postgresql or oracle), the DBDaemon process may write to a monitor log file indefinitely, including after the monitor log file is rotated and/or deleted.
The DBDaemon process may write debug logging messages to the affected monitor log file indefinitely, including after the monitor log file has been rotated and/or deleted. As a result, storage in the /var/log volume may be consumed to the point that other logging cannot be performed, and the BIG-IP instance may be restarted/rebooted.
This problem may occur when: - using a database monitor (mssql, mysql, postgresql or oracle) which is configured with the "debug" value set to "yes" - using a database monitor (mssql, mysql, postgresql or oracle) for a pool member which is configured with the "logging" set to "enabled"
To work around this issue, restart the DBDaemon process. To find the PID of the DBDaemon process, observe the output of the following command: ps -ef |grep -v grep | grep DB_monitor.jar | awk '{print($2)}' To confirm whether the DBDaemon process is writing to a monitor log file, and if so, which file: lsof -p $(ps -ef | grep -v grep | grep DB_monitor.jar | awk '{print($2)}') | grep -e COMMAND -e '/var/log/monitors' To kill the DBDaemon process: kill $(ps -ef | grep -v grep | grep DB_monitor.jar | awk '{print($2)}') NOTE: Killing the DBDaemon process will cause a short-term loss of database monitoring functionality, until DBDaemon is restarted by the next database monitor probe.
