[Bubblemon-list] Re: Another stack trace

[Johan Walles]

OK, now we are getting somewhere :-).  The problem is that load has been 
measured and been found to be above 100%.  That triggers an internal 
consistency check.  That is where the following printout comes from:

** ERROR **: file gnome1-meter.c: line 145 (getCpuLoad): assertion 
failed: ((loadPercentage >= 0) && (loadPercentage <= 100))

I am about to change that logic to say that any load > 100% should be 
considered to be exactly 100%.  This will resolve your problem.

However, I'd find it quite interesting to know exactly how much over 
100% your load is measured to.  I assume it's something like 103% due to 
some rounding error or other, but if it is like four million or 
something, just rounding it to 100% would seem a bit crude.  Since the 
assertion says that it failed in function getCpuLoad, if you go do 
"frame 5" (because line #5 in the stack trace says "getCpuLoad") and 
then "info locals" in gdb, the exact percentage will be shown.  If you 
can do that and e-mail me the result of "info locals", that would be 
very interesting.

  Cheers //Johan
