Symptoms

"Error: the operation timeout" message when fail to connect to SmartConsole.
High CPU utilization by the CPM process.
From fwm.elg: 2019.02.19_18:45:10 - FWM mainloop wasn't available for 1016 seconds. This may cause UI / Server slow down
[FWM 4207]@MGMT[19 Feb 19:02:06] Time consuming warning: fwm command [calculate-internal-network] took 1006 sec
Increase in Java memory heap size. sk123417 does not resolve the issue.

Cause

The "calculate-internal-network" command is a part of the FWM process that creates a large number of get objects. In rare cases, this can result in extremely high CPU utilization.

This will cause the CPM process to become unresponsive, and then result in a failure of the CPM process and the FWM process.
