AlexZap Posted August 20, 2023 Author Share Posted August 20, 2023 ok, thank you, but when the used ram(not the cached) reach 100% the system become unresponsive and every action on the webpage take a very long time to load. Quote Link to comment
JorgeB Posted August 20, 2023 Share Posted August 20, 2023 Then there's likely some app with a memory leak, post the diagnostics when that happens to see if there's something visible. Quote Link to comment

Solution JorgeB Posted August 21, 2023 Solution Share Posted August 21, 2023 Try updating to v6.12.4 once it's out, there are some ipv6 fixes. Quote Link to comment
ApfelBirneKreis Posted October 1, 2023 Share Posted October 1, 2023 same problem here even with 6.12.4 Quote Link to comment
Bremsklotz Posted November 4, 2023 Share Posted November 4, 2023 I had the same problem. After a couple days my ram became full and I had to restart the server. Otherwise the system was unresponsive. I used Netdata to find the cause: there was something like memory-dhcp which used a lot of ram. I think it was a network misconfig. I solved it like this: settings --> network --> ip adress assign for ipv4 and ipv6 from automatic to static settings --> docker --> advanced view --> deactivate custom ipv4 and ipv6 network on br0 No problems since I changed that.
