Container Memory Leak?

RouterOS Containers
1

Today, I installed Technitium DNS via the App menu on my RB5009, with the disk being an SSD in a USB 3.0 enclosure. This is my first attempt at using containers on MikroTik.

Technitium’s memory usage consistently stays around 240 MB, but the overall RAM usage on the RB5009 keeps increasing over time.

Before installing any container, the router’s RAM usage was around 150 MB. After installing Technitium, it increased to about 360 MB and then began to rise gradually. After seven hours, total memory usage has reached 520 MB, even though Technitium itself is currently showing only 238 MB of usage.

Does memory usage stays stable without container or does it grow up to max available memory?

Without container, it's stable even after running for months. But again i installed 7.21 only today to try container apps.

So stable memory size was before 7.21 ?

Yep. Haven't tested yet without container yet. Will update tomorrow.

Have one more Rb5009 running for last 7 days in 7.20.7 without any containers. RAM usage is stable and free showing around 860MB.

Monitoring for the last two hours without any container, RAM usage is stable around 155MB!

Upgraded to latest beta and also changed to pi-hole container, for the last one hour there is no increase in the RAM. I guess the memory leak is in Technitium.
