We've had some terrible experiences with RPD due to NSR sync. to re1 for 
BGP, on an RE-S-1800 running Junos 20.4R3.8. Turns out the code can't 
deal with grouping outbound updates to eBGP neighbors at scale for that 
RE, which crashes RPD on re1.

The options were to either disable NSR, rewrite our outbound policies 
and combine multiple customers in the same outbound group, or get more 
memory. We went for the last option.

No more problems on the RE-S-X6-64G.

Juniper have some work to do to optimize the code in these use-cases.
