Core: 201: Memory problems after switch on DNS Firewall

ritchie · 2 June 2026 14:57

Hi,

after I had installed the install the Core 201, I switch on the DNS firewall.

About a week later, my system runs out of memory (system with 16GB), because of the DNS Firewall. I used suddenly more the 1.6GB memory.

DNS service did not run and I had to disable all settings in this screen to get the system back in operation.

Is this a know issue and will maybe core 202 fix it ?

Best regards
R.

Please see this thread from the beginning of April.

Yes it is a known issue. No it is not fixed in CU202 but it will be fixed in CU203 with the replacement of unbound with knot.

The simplest workaround is to disable the DNS Firewall and wait to use it when CU203 is released.
