Hi All,
I have a queer problem.
This is happening on a freshly installed RH7.1 notebook. Celeron 400 + 64 mb ram, kernel as shipped (2.4.2-2, have not even recompiled it yet). I have a 140 mb swap partition set up but at the time this happened it was OFF. I was (still am) running X + twm + two xterms with ssh + netscape (this is probably the cause of the entire problem). I had a single netscape window open with a mid-graphic intensive screen. The system started thrashing... Now my question is how can it be thrashing with swap explicitly turned off? [oh just to make stuff even funnier netscape is at nice -19 (i.e. lower priority)]
top gives me: mem: 62144k av, 61180k used, 956k free, 0k shrd, 76 buff, 2636 cached swap: 0k av, 0k used, 0k free [as expected]
cpu states: 0% user, 99.9% system, 0.0% nice, 0.0% idle
process list: 99 % cpu, CTIME: 29:24 kswap...
all other processes have decent time and cpu usage lists even X has a CTIME of only 11 minutes [well init has 260:10 but that is normal..., system has been up 3 days]
So my basic question is what can I do to fix this?
I expect (only explanation I can find) that the problem is Netscape mmaping files.
Oh, and Netscape is not dead it is just very slow [like the entire system, I can watch top refresh the screen in line by line mode...]
Any help would be appreciated...
