[Solved] Memory usage of AdGuard is 548%

llaumgui · November 25, 2020, 4:10pm

Hi,

on my Luci interface and top interface, I have a process (AdGuard) with an usage of 548%... But my Routeur (Xiaomi Redmi AC2100) is OK. Where is the true ?

How many domains are being blocked?

The value comes from "top" command in busybox.
/bin/busybox top -bn1

You might run it and compare the output to LuCI.
It may be parsing error.

The code in LuCI is starting from here, and the parsing/matching string is a few lines below.

This is result of top:

/bin/busybox top -bn1

...

I have free memory... But 548% from AdGuard...

free
              total        used        free      shared  buff/cache   available
Mem:         123772       76580       21672       12660       25520       11280
Swap:             0           0           0

 ps w | grep Ad
 1000 root      663m S    /usr/bin/AdGuardHome -c /etc/adguardhome.yaml -w /tmp/adguardhome --no-check-update

On this screen, you can see impact of AdGuard... But I have free memory...

VSZ is Virtual memory size. It means AdGuard has reserved 663MB of address space, but the most of it is not committed, and so no backing memory or swap is needed.

llaumgui · November 26, 2020, 12:11pm

Thx. I look how reduce this reservation.
