RAM Creeping | Top Command info contradictory

27 Apr 2023, 15:53

Hi,
In My Project , I am using RevPi connect + [32GB].
I have Node-red and Codesys running in my hardware.
The response of the TOP command is contradictory between the available RAM and the individual Application RAM consumption.
TOP_CMD_RAM_Individual_applicaion_MEM%.png
TOP Command
TOP_CMD_RAM_Individual_applicaion_MEM%.png (751.59 KiB) Viewed 1201 times
In the Above image, the as per the Free memory shows approx. 10% of the total memory , but this not not getting matched with the summation of the individual application memory consumption. [Example : 28.6 + 5.7 + 2.4 + 1.5 + 0.6 , etc ... ]
Does any other application runs in the background and which is not getting captured from TOP command, How can i find which application consumes these hidden RAM ?
Any lead would be highly appreciated !!!

Best Regards,
Mani

Hi Manni, take a look at this page - a discussion about how the command top calculates the memory space and the free space:
