Balance 2500: Applying changes to LAN breaks all PepVPN sessions

We are experiencing a problem where whenever we remove or modify a single LAN we break all of our PepVPN connections originating off of the same router for about 10 seconds. For example if we remove or modify any LAN IP address, even if we delete it we break almost all others. This has been very disruptive and we would like to know how to prevent it.

This is out of the expected behavior. Can you please open a support ticket here for support team to check further ?
