On the numlock issue...
There was a week when I got no freezes, that was after 2.4.2-pre1
so I looked around and tried to find the reason (2.4.1 freezed)
The only thing I could find was this...
But now they have reappeared!!!
I have started to use xosview on top to get a feel for what is happening.
The situation after freeze has been similar (2 captures with xosview this far
one with KTimeMon
_Programs running_
term (konsole) running
xosview
kppp
kmail
konqueror
(started in quickly one after another)
Load above 1 (latest CPU0 has been different 100% and 9%)
MEM 91M (both times!)
SWAP 0 (could be a rounding problem in xosview)
PAGE 0
INTS 0,4 (one time 15 the other time 12)
The MEM & SWAP is interesting.
I have 96M RAM. Lots and lots of swap space
"Adding Swap: 530136k swap-space (priority -1)
Adding Swap: 133048k swap-space (priority -2)"
Cache was about as big as USED+SHARE, BUFF only
a few precent about the size of FREE.
When the freeze happened MEM was rising, I wonder if
I got the freeze when hitting swap...
I retry with wider xosview...
