recently, my fedora 8-based gateway laptop will, for no obvious reason, suddenly go berserk in terms of disk activity, to the point where it effectlvely becomes unusable -- that is, simple keyboard activity takes over a minute to get a response. it just happened again, at which point i switched out of my gnome desktop (it took over two minutes to get back to a virtual console), where "top" showed nothing in particular hogging either memory or CPU, but it also showed a 5-minute load average of over 20! "free", on the other hand, showed both memory and swap to be maxed out in terms of use. the standard disgnostic tools didn't identify anything as the culprit, so i just killall'ed firefox-bin, and everything returned to normal, at which point "top" showed that two instances of npviewer.bin were now hogging over 50% of the CPU. at this point, i'm convinced that npviewer.bin is an evil, evil piece of software and i'm sorely tempted to get rid of it. is anyone else seeing this kind of bad craziness? rday p.s. firefox, in general, has been impressing me less and less as time has gone by. after i finally killed it above, once again, it left a youtube image embedded firmly in my desktop, which could only be cleared by logging out of X entirely. i think it's finally time to switch browsers. ======================================================================== Robert P.
