Traffic can be directed to an less specific virtual during virtual modification. It could also be dropped if there is no less specific virtual server.

No known workaround at this time other than applying configuration changes in a manner that avoids doing them on a unit that is handling the traffic. Applying changes on the standby and then failing over and syncing or utilizing a maintenance window would be common schemes to achieve a separation between production traffic and configuration changes.
No fix available at this time.
