Network connections to Messaging Gateway randomly fail or disconnect

Products

• Messaging Gateway

Issue/Introduction

Connections to the Messaging Gateway Control Center or Scanner host appear to randomly get reset or disconnected. Web browser or ssh connections will operate normally for a period of time but then will be disconnected.

Environment

Release :

Component : network, arp

Cause

This is often the results of an IP address conflict on the network. Another host or device on the network is configured with the same IP address as Messaging Gateway.

Resolution

To confirm whether a duplicate ip address exists on the network, shut down the Messaging Gateway appliance and then attempt to ping the SMG IP address. If the SMG IP address can be pinged when the SMG system is shut down, another device on the network has the same IP address.

Messaging Gateway cannot share IP addresses with other devices on the network. Either the other device must be reconfigured to use a different IP address or SMG must be configured with a new IP address.
