Hi,

I'm running some scalability tests for OSPFv3 using Bird in docker 
containers. I'm getting some error messages in the logs if I run too 
many instances.

2017-04-20 21:59:57 <ERR> ospf1: Socket error on ln971_if1: Invalid argument

I have 1000 nodes connected linearly (each node connects to two 
neighbors except the two end nodes that connect to only one neighbor). 
I'm running Bird 1.6.2 with a kernel version 4.9.0. Is this a memory 
limitation? Kernel bug?

I'll attach the first few lines of the log file.
