[dnsdist] expected file descriptor usage

[Christoph]

Hi,

we run a small DoH server using dnsdist
and are observing an almost linear growth
of dnsdist's file descriptor usage
(initially about ~1k/day now down to ~500/day)

Is this expected behavior?

What will happen when it hits the limit
of 16k?

from the systemd service file:
LimitNOFILE=16384


thanks,
Christoph
