There are two problems here.

The first problem is that in /usr/share/init/tcsh/logout (the default 
user logout script on Mac OS X), there is a line "if ({ (klist -s >& 
/dev/null) }) kdestroy".  This is probably where your klist is being 
run from.  As a workaround, remove that line, and you can put the 
klist back in /usr/bin.  Since you installed KfM 4.0, I imagine you 
want to use it.

The second problem is that klist isn't immediately terminating. 
Since we've never seen this problem before and are unable to 
reproduce it here, I'll need some information from you:

(1) Did the Kerberos for Macintosh 4.0 installer report any problems 
installing?  If you hand-installed the binaries, what tools did you 
use to copy the binaries into their installed locations?

(2) When klist is running and consuming your CPU, is there a 
CCacheServer process running?  If so, what arguments is it running 
with?  You should be able to get the arguments from "ps".

(3) What (if any) are the contents of 
"/Library/Preferences/edu.mit.Kerberos" and 
"~/Library/Preferences/edu.mit.Kerberos".  Are these files readable 
by you?

(4) If possible, try running /Developer/Applications/Sampler.app or 
gdb on the pid of your klist process when it's eating 50% of your 
CPU.  A backtrace of klist in this state might be useful, even if 
some of the entries are unknown (the binary is stripped).

(5) What happens when you launch /Applications/Kerberos.app.  Are you 
successfully able to get Kerberos tickets from Kerberos.app or 

Thanks for your feedback,
