Isn't this in the FAQ by now? Guess not.
kvm_open() typically fails for one of two reasons:
1. You're running gmond as a regular user (this won't work).
2. You linked in a 32-bit version of libkvm which is trying to open the
symbol table of a 64-bit kernel.
3. Something horribly, horribly wrong has happened. Grab a crowbar and
prepare to fend off head crabs.
From your debug output, it looks like #2. Set yourself up with a
compiler capable of generating 64-bit sparcv9* binaries and everything
should work.
Unless, like the situation for the other person who just posted, it
doesn't...
BTW, I was under the impression that we brought back a couple of command
line options as of a VERY recent 2.5.x version. All my monitoring cores
are behaving properly so I haven't had reason to investigate this for
quite a while, though...

Yes I am running as root. Why is it complaining about /dev/ksyms not being
32-bit? Am I missing a configure option?
Thanks Again,

Any suggestions?
What does 'gmond -d 99' say? Is it coredumping or quitting?
Also, make sure you're running it as root.
But yeah, without the debug output we're all just randomly picking from
the Grab Bag o' Fixes, which makes our advice only slightly more likely
to help you than any random thing a first-tier dialup tech support rep
could offer...
