Hi Daniel, Anand
I am running knot from the copr fedora repo.
I managed to get knot 3.4.0 running with mod-rrl in global-module.
I had mod-rrl mentioned twice, in global-module and once in module. I
made a mistake there.
I did some further tests with 3000 zones.
Knot version 3.3.9 in with mod-rrl global-module uses 140MB memory.
Knot version 3.3.9 in with mod-rrl in module uses 200MB memory.
Knot version 3.4.0 in with mod-rrl in global-module uses 170MB memory.
Knot version 3.4.0 with mod-rrl in module crashes with out of memory.
(it uses more then 7GB memory before it crashes)
I understand that I should run mod-rrl in global-module, it seems more
evident.
I think it is resolved now, thank you for your help.
Thank you.
Kind regards

Are you sure there was just one mod-rrl instance
(global-module)?
Based on
https://www.knot-dns.cz/docs/latest/singlehtml/index.html#table-size
one module instance consumes approximately 8M.
There are no additional dynamic allocations in the module.
I see the module is statically linked. Do you compile Knot on your own?
BTW, how do you know it leaks memory?
