Commit 54fe75b9 introduced a regression in 9.11
This commit causes a problem in 9.11 when using query-source
with port 53
.
After a reconfig or reload the server will stop receiving data.
I've confirmed that 9.14 and later versions are not affected. I've also confirmed that both 9.11 and 9.11-S are affected.
This was discovered from a customer ticket, though the customer has since removed the query source port configuration.
