If something has sucked up the memory and the application is paging off disk for example. Look for any processes which are taking up a lot of memory (run away firefox, chrome etc) Can you run vmstat 1 in a terminal window while this happening too please. I've also seen this with driver problems causing the kernel to have some kind of problem (page faults, oops etc). For /var/log/messages I'd egrep 'warn|err' /var/log/message Also try looking in the X log file(s) (/var/log/Xorg.0.log and ~/.xsession-errors) It is also possible your disk is dying and the errors cannot be written out. You could try checking if there are hardware problems (perhaps run your dell diagnostics disk). gene -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
