I noticed just be for my Orange Pi PC2 became unresponsive that the KswapD command was using the CPU heavily and had used a massive amount of the total CPU time.
From the research I have done I am not entirely sure what the cause is.
About two years ago there were similar sounding problems caused by a bug in kernel. Given I am running the latest non-stretch image, would I be safe to assume that this problem has been resolved?
Other possibilites include problems with the configuration of the swap file, a lack of physical RAM memory or a program going rogue taking up too much RAM.
Currently with the system running on a relatively light load it has the following conditions:
