This issue affects Fuel 4.1.x and Fuel 5.x as well. Need to fix in both cases.

We have simple Neutron config for any environments - and the same configuration for OpenStack on 2 VMs in Virtual Box and for 50 berametal servers.
As a result all works cool on small environments and doesn't work on production environments: we can see many errors in log files and looks like we can fix it - to do this we need just update several parameters in Neutron configuration: need to increase the number of API workers and also encrease the pool of requests to data base:

/etc/neutron/neutron.conf:

[DEFAULT]
...
api_workers = 1 + compute_nodes_count (or just 50 - we use this value and all works good)
...

[database]
...
max_pool_size = 10 + compute_nodes_count*5 (or just 200 - we use this value and all works good)
