Thanks. I believe that the entire feature has received very poor = testing. Considering how many people have stated how important it is to = them, really critical issues have been reported very late in the release = process which indicates that the feature has not been tested, or if = people found those bugs, they have not been reported. I have to say that I am very disappointed about this. But it has nothing = to do with your question. > - Each 'save' in WUI page increases the memory consumption. Even if = nothing changed. A restart of unbound frees this huge allocation. Yes, this is known. It is a problem inside Unbound and there is nothing = we can do about it. I did not report it to Unbound, but I am sure they = should be made aware. Unbound in general is using a lot of memory when it is downloading the = lists. I have imported the lists into PowerDNS Recursor and it raises = its memory consumption by about ~300 MiB when Unbound is going into = 1.6-1.7 GiB.

I found cases where this isn't true. A = unbound restart yielded the right behaviour. >=20 >=20 > I must apologize not to have tested the release.
