hi,

got the following oops from 2.2.14-5.0 (redhat 6.2 distribution), ntagent, a system monitoring process, may be the
trouble-maker, however, i think it's innocent, and the system stack somehow got messed up.  i know that the information
here may not be enough to locate the problem, but that's almost all i have got (i dont even know how to reproduce it).
wonder if someone could kindly give me some hint on how to decode such message (especially the stack tracing part), i
tried ksymoops and read oops-tracing.txt, still cannot understand it.
