Almost any time people report "low memory" its because they are applying windows knowledge to linux.
In the linux world, any memory not used is considered wasted, and will be put to use for file caching and backgrounding tasks.
Indeed. There are a few applets that will show memory/cpu/swap use If your memory (in-use + buffers + cache) isn't up in the >90% then something is wrong! Yes, perhaps only 60% (at some particular snapshot time) is being used by the programs' working set, but so what? I *do* have just such an applet in place and see the swap use creep up over time when I'm using firefox. I think it has a memory leak. I shut down firefox and the swap drop back to close to zero. I can do a swapoff/swapon to clear it. Yes, my laptop freezes occasionally now I'm running 11.4. Sometimes I can't even ssh in. Sometimes I can ssh in but the shell is unresponsive. Sometimes - not often - it works and I can init-3/init-5. I have to do that because the double-ctl-alt-backspace does not unfreeze the machine. More often that not such freezes require a hard reset. -- It is the first step of wisdom to recognize that the major advances in civilization are processes which all but wreck the society in which they occur. --Alfred North Whitehead -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
