About a year ago I reported the kswapd0 running out of control on OPi PC and Igor, after couple of tries made it behave. Today, I got OPi One loaded with the latest 5.26 Ubuntu D/T and the OPi PC2 with today's daily Ubuntu D/T and both demonstrated the following behaviour when pressed for memory:
Specifically, running a "make -j2", when the available RAM got below 38000, the kswapd0 started getting more cpu time and eventually everything stopped waiting for disk I/O (80% wa displayed in "top"). Interestingly, not a single byte of swap storage was used.
I tried different combinations of programs and everything worked fine until the demands on RAM got the available RAM below 38000. The sure fire combination were a long make (with just one thread) and FF displaying the finance page of yahoo!
This behaviour is, I dare say, identical to the one I encounter a year ago. Any ideas?
Please, let me know if you need any more information.
