I'm aware of that. Fortunately, we do not use Simultaneous-Use on our
most busy radius-servers, so I can safely turn this feature off. It might
be a good idea to issue a warning in case the Simultaneous-Use attribute
is used in conjunction with "system-accounting no" (or even a crash at
startup). The least we could do is write good documentation for it. 

I'm pretty convinced that the feature should be added to the server, 
since it has been _very_ benificial for our overloaded radius systems.
This afternoon I activated the patched server on one of our radius servers.
This one has had loads up to 5, due to the system accounting. We have 
been able to bring that back in the last weeks to 1.5 by using a cron job 
which periodically emptied the utmp and wtmp files, so going through them 
would cost less. I bet you can guess from our load graph for today (which is 
linked below) at what time I activated the patch. Give it a try...

As you can see, the server load has gone slightly down by disabling
the system accounting.
