 Thanks to Justin who pointed out that lockstat has replaced kgmon.

Subject: Kernel Using over 50% of CPU

We've been having performance problems on one of our servers recently,
and doing a top shows the kernel using over 50% of the CPU.  This is
unusual, and is not this way on similar systems performing the same
function.  I'm trying to find a command to show me what kernel
subsystems are using the CPU, but the only thing I've found is kgmon
which is very old and doesn't seem to be included with Solaris 8.  Any
idea what I can use?
