That depends on what you meant by upstream.

On Ubuntu, the limit of open fd is set to an higher value via the
systemd unit file. It does not look like devstack (OpenStack) is
changing this.

In devstack, I've seen an increate of the limit of open fd, but via
systemd, so for all systemd services.


As for the memory limit, it was necessary with a host of 4G of RAM. But
I did not try again with the default limit and a host with 6G of RAM.
(The default is 0.4, here I've set it to 0.8)
