## Symptoms

- The LOM KVM console connection to the Security Gateway disconnects with a "Video Socket Error: Abnormal Termination" message while a network scan runs with Qualys or a similar scanning tool.

## Cause

A network scan sends an extensive amount of packets that creates a dense connection and causes the KVM console connection to disconnect.

2. Perform a cold boot of the LOM card:

   `[Expert@GW:0]# ipmitool mc reset cold`
3. Stop the IPMI service:
