Help with some errors in logs

Installing and Using OpenWrt
1

Hello all..

I need help with some errors in my log… I try to search in the internet, but I found the explanations very confusing and I couldn't apply them to my system...

My system is ruuning the last version of Openwrt with some services included…

1st problem - Adguardhome - I have this errors:

2nd problem - nmdb or Samba4 - I have these errors:

I don't know how to explain it better, but I'm noticing a certain slowness in every task I run on my x85 router, which has a Core i5 CPU with 8 GB of RAM—I think it shouldn't be slow, but given the numerous errors, I'm at a loss for words.

This installation was completed without any package updates, and yet I'm seeing kernel errors as described below, which might be helpful...

Helo @anon63541380 …

No, none overclocking involved. This hardware is old All in One LG PC… the screen is broken, but the cpu, a Core I5 with 8 Gb Ram is OK, I make my router based in x86…

I don´t upgrade packages yet… I install the original package that I download from site and install…

Well, it is up to you to explain forced drop_caches

and the “dns” crashing in packet capture library

It does not happen on default OpenWrt.

What packages you got installed?

opkg list-installed

Swap it for a normal router, this one promises to burn 1$ a day in electricity alone, dead screen probably saves half of that…

Hope you can find one in your countrys electronics stores.
