Wow. That's a lot.

Have you set something up to restart it periodically, or
are you going to live with the memory leaks? I think that
having auth-perl shut down and restart the perl
interpreter every so often should help, though it's not
necessarily true that this will prevent the memory leak
altogether.

Hmm. A `convergent billing platform'. I don't know what
one of those is, but I imagine you're right: I don't think
I'd like it....

I'm glad you find it useful.
