IPv6 BGP peering crashing routed daemon

I'm currently setting up BGP peering over IPv6 with our ISP, who is sending us the full IPv6 route table (apprx. 61k routes). The BGP session establishes, and I receive route updates from the ISP, but within 60 seconds of the session establishing, the routed process seems to crash, and the BGP session resets. 


Looking in /var/log/routed_messages it's full of errors saying: “Dec 19 14:03:39 ERROR:   KRT SEND ADD    2620:1c0:61::   mask ffff:ffff:ffff:: router 2606:xxxx:xxxx::5: Cannot allocate memory” 


As far as I know there's no tuning to be done as far as memory allocation goes, so is this a bug in routed? This is running on a 5400 gateway with 8GB RAM, and usually only 40-50% consumed.
