What

When SO_REUSEADDR is set, then multiple process of device with small chance system can peak same port for coap, coaps, coap+tcp, coaps+tcp.

Note

For linux it is fixed by PR: #56
For other ports it's need to be implemented too.

Replication:

It is replicable with 1000 processes (one per device) via docker with network host - cca 20 ports are shared among devices.

Priority

Trivial - linux is used mainly for docker, so for other ports it is unusual to multiple processes of devices.
