>
> When there is out-of-band movement of VRs (due to native HA in a VMWare
> cluster), they need to be rebooted for reconfiguring all the network rules.
> Currently all these VR reboot happens using the thread pool used for
> collecting VR statistics.
> Refer VirtualNetworkApplianceManagerImpl.java
> _executor = Executors.newScheduledThreadPool(1, new
> NamedThreadFactory("RouterMonitor"));
> Also as can be seen, the size of the pool is 1. So if there are multiple VRs
> getting moved out-of-band, the reboot for each will be queued up.
> The idea is to use a separate thread pool for handling VR reboot.
