Model: TL-SG2008  
Hardware Version: V4
Firmware Version: 4.0.3 Build 20220624 Rel.60744

Some time back I noticed that this switch TL-SG2008 v4.0 fw 4.0.3 Build 20220624 Rel.60744 had gone offline in controller dashboard. I could not either ssh into it. It was still switching alright, otherwise I would have noticed it sooner. (Since I have AP's going offline/online daily, the controller message of switch went unnoticed.)

 

Rebooting restored things back to normal. However now that I'm somewhat aware of the situation, I noticed that switch memory usage had increased from 57% to 60% in 6 days (controller only stores 7 days of history). I think after reboot it started from 53%.

 

So possibly there's some new bug in the latest fw as the previous version didn't show IMHO this behaviour.

 

Feel free to suggest how to provide more info as necessary. This switch is in pretty light use with only 3 ports connected. Controller is currently 5.6.3

  @mikahe Issue is most likely fixed by firmware updates to TL-SG2008 v4.0 fw 4.0.6 and TL-SG2008P v3.0 fw 3.0.4. Both have RAM consumption steadily at 45%

You can try to disable SSH to test, check this:

It looks like disabling SSH did not at least stop the memory creep. I have also another switch TL-SG2008P v3.0 fw 3.0.2 Build 20220909 Rel.75248 where the increase rate as % is 2-3 times slower than with TL-SG2008 v4.0, but both show increase over time.
