High memory and CPU usage

### Prerequisites

- [x] I have checked the [Wiki](https://github.com/AdguardTeam/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) and found no answer

- [x] I have searched other issues and found no duplicates

- [x] I want to report a bug and not [ask a question or ask for help](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a)

- [x] I have set up AdGuard Home correctly and [configured clients to use it](https://github.com/AdguardTeam/AdGuardHome/wiki/Clients). (Use the [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions/categories/q-a) for help with installing and configuring clients.)

### Platform (OS and CPU architecture)

Linux, AMD64 (aka x86_64)

### Installation

Other (please mention in the description)

### Setup

On one machine

### AdGuard Home version

v0.107.73

### Action

High memory and CPY usage during a couple of hours every day. This issue started after upgrading to "v0.107.73".

I have 512mb allocated to AdGuard Home and have never had this issue before the upgrade.
RAM usage is normally around 300mb and for CPU, below 1%
The high usage starts at around 9-10pm (09:00-10:00). I can see small peaks before the upgrade but never to this extent.

Cant find any settings that starts anything daily during that time.

`journalctl` during those hours today (2026-03-13):
