Hello: I don't know where to look for even getting started on this odd situation.
I am running openSuse Linux Leap 15.5 (up to date on software) on a 32 gigs main memory. Currently the programs running are 22.9 tasks average consuming 2.89 gigs of memory.
When I go to type a command in the konsole window, sometimes things will freeze, like the whole system is halted for a few seconds, then things will resume forward from that point. The effect is like someone stuttering, or temporary paralysis affecting the whole system. Sometimes I am forced to wait a few seconds before things resume again.
I am using the KDE Plasma desktop. I particularly notice the problem when I will do tab completion or when I hit the backup key. I did check the etc/completion.d folder but don't really know what to look for or what is considered normal.
Any ideas? I am totally puzzled by this strange behavior. I notice that the clock icon keeps ticking just fine (when the system went into swapping, sometimes the clock would freeze, so it's not that situation) but you are forced to wait until the freeze-up goes away.
