VIAVI TestCenter: ARPing all stream blocks on LAG (port grouping) ports causes GUI to crash

• After LACP is brought up on  each set of aggregated ports (see port setup in Environment section below) • All stream blocks are selected and "Start ARP/ND" is executed • After about 10 minutes Spirent TestCenter (STC) crashes • When logging into the ports (using root access) we see that the generator daemon on the 8-port port group was at 100% for most of the time and at times even higher From ui.log 17 Aug 2016 18:03:38,496 INFO  6        - user.arpnd         -  Learning is in progress on 1 ports 17 Aug 2016 18:03:38,496 ERROR 6        - user.rpc           - Timed out waiting for Generator_3.DoSQLFaster response after 600 seconds.
