OPERATIONAL DEFECT DATABASE
...
...
unable to view events (connection, intrusion, malware, file, Security Intelligence, discovery, user) on the Firepower Management Canter (FMC) GUI. High CPU use on the FMC -- specifically, by MonetDB Errors of "Cannot allocate memory" appearing in the logs for MonetDB (/var/log/monetdb/merovingian.log).
A significant volume of incoming events on the FMC
A graceful restart of MonetDB. 1. Log into the CLI of the FMC. Go to expert mode. 2. Execute the following command to restart MonetDB (when prompted, enter the password for the CLI user): sudo pmtool restartbyid monetdb
If this specific set of symptoms is seen on the FMC, restart MonetDB first. Do not first attempt to rebuild the event database, as doing so may not be necessary.
