DNS forwarder crash

Hi Folks,

I seem to be having an issue with the DNS forwarding process on a CCR1072 running 6.49.8.

The symptoms are that it stops answering DNS requests. Attempts to interact with DNS settings either in WinBox or on the CLI fail:

[xxxx@yyy] /ip dns> print

action timed out - try again, if error continues contact MikroTik support and send a supout file (13)
[xxxx@yyy] /ip dns> print

action timed out - try again, if error continues contact MikroTik support and send a supout file (13)

[xxxx@yyyy] /ip dns> export
# jul/27/2023 15:20:27 by RouterOS 6.49.8
# software id = ....-....
#
# model = CCR1072-1G-8S+
# serial number = 8A....
#error exporting /ip dns

The router will sit in this state for 5 to 10 minutes, then the issue seems to clear itself for a while.

I have generated a supout file during the issue if Mikrotik support want it.

Has anyone else seen this?
