[Observium] Internet 512k global routes

With the Internet hitting 512k routes, I was looking in observium for the IPv4 prefixes for our Brocade XMR routers.  I'm getting a draw error on all prefix updates.

graphs/type=bgp_updates is working ok.

graphs/type=bgp_prefixes_ipv4unicast or any of the prefix graphs are not.

I've tried on observium version 5728 and CE version 5229.

Is anyone else using XMR, CES/CER, or MLX routers getting the same thing?

Thanks, Ken
