Does top show the amount of memory that you expect? What's using all that memory? Swap should be empty or close all the time if the system has enough memory. Is there a background task that is using a lot of CPU? The locate database program can use a lot of IO as it scans the disk for things. You could check the logs for messages about kernel errors because of hardware (journalctl) and run the memory checker to be sure your memory is OK. My /boot shows two, memtest86+-5.01 and elf-memtest86+-5.01. > Nothing has changed in the system workload or configuration. Sure sounds like a hardware issue showed up. Try cleaning the case, and reseating the memory and connectors. Temlakos makes good points about the hard drive, too. All the new writes during upgrade could have brought out issues. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
