systemtap crashed the kernel
Folks,
I consistently run into the following coredump while I have
my script running to monitor NFS traffic. The core stack is
as following:

I can reproduce this with "version 0.5.8 built 2006-07-14" and earlier
version that comes with redhat 4 update 3. Is this a known issue? Any
comments?
Thanks,
