after upgrading to 2.7.2 Unbound not starting.

[jackieboy]

there is this line in the generated config that is causing an issue.

sock-queue-timeout: 0

It is reporting this as a keyword it does not know.
It is saying that ":" is stray and that "0" is another unknown keyword.

for now I have set the /var/unbound.conf to readonly and have manually commented that line out of the conf and manually started unbound.

Any help in resolving this is appreciated. Thanks.
