I was on 7.13.X previously, never had this message in the log.

I don't use cache on DNS queries (it is cached upstream) so my config is this:
Since 7.14, I get a lot of spam in the logs on every DNS request:

cache full, not storing

buffer: memory
topics: dns, error

Please allow us to disable the cache in some other way or revert the log message!

What device are you using ?
If it is a device with 16Mb storage, 7.14 can be a 'challenge' depending on your config.

Side note:
If you do not want to use dns cache at all, you may also want to change this Set to no.

From Help pages

allow-remote-requests (yes | no; Default: no)
Specifies whether to allow router usage as a DNS cache for remote clients. Otherwise, only the router itself will use DNS configuration.

1) It has nothing do to with device memory

2) It has nothing to do with allowing remote requests

3) So you already know the answer.

Yes they introduced a bug where when making a DNS request that can't be added to the DNS cache, it thinks the cache is full when the TTL is just actually 0 (the only way to disable the cache).

It has nothing to do with my 423.0 MiB available on device especially when the log outputs to memory as reported.

It has nothing to do with allowing external requests to the DNS server.

... the sad thing is, that this bug hasn't been fixed either in 7.14.1 or in 7.15 beta6

EDIT: Nope, message re-appeared after one day, still have the bug
ORIGINAL MESSAGE:

I don't know about you but I don't have the messages anymore in 7.14.1

I wonder if their support is aware of this issue or should a request be open...?

In case of doubt, always create support request incl. supout.rif.

I am seeing this as well since upgrading from 7.13 this week. I have created a ticket in reference to the issue.


I found disabling "allow remote request" and re-enabling it seems to fix it. I am not certain if that's temporary or not.

edit: scratch that, it started again..

I've also opened a support ticket and linked them to this thread. Will see how it goes.

Ya i have yet to get a response.
