Output from /proc/stat normal Red Hat 7.3:  
intr 3030199 2250856 18029 ... 
Output from /proc/stat Red Hat Linux Advanced Server release 2.1AS: 
intr 10974542 1009005264 1000000060... 
rstatd compares if first number of intr-line is bigger than second 
number. If this is not the case assert() is called. 
Second problem seems to be, that sscanf() can not handle NULL pointer 
as first argument, therefore i added tests for NULL pointer in front 
of each sscanf line 

Comment 3 Phil Knirsch 2002-12-05 10:52:02 UTC
OK, verified that the patch for rstatd.c for later kernels fixes the problem.

Will open a new AS errata today and build updated packages.

Read ya, Phil
