In very few cases, usually when I've opened around 100 Tabs with "Flash" stuff inside, the browser becomes unresponsive and needs to be killed. Still the CPU load is low, but I assume a lot of swapping takes place. It looks like this: 1 [|||| 7.9%] Tasks: 73, 0 thr; 1 running 2 [| 2.6%] Load average: 0.38 0.70 0.42 Mem[|||||||||||||||||||1601/1990MB] Uptime: 00:52:33 Swp[||||| 275/2047MB] Short time later: Mem[|||||||||||||||||||1597/1990MB] Swp[|||||| 404/2047MB] Then I have to kill -9 the processes "operapluginwrapper.linux" which works. I tend to use htop for this, PF9 9 Enter. :-) > I keep lots of tabs open so I usually end up with a massive amount of > these things running and consuming a very low amount of CPU usage -- and > as you stated -- quite a big chunk of memory too. > > Doing a 'killall -9 npviewer.bin' every so often solves the problem for > me. This matches my observations. How does the (running) Firefox react to the measure you've taken? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
