Fwd: Re: Fwd: RE: (RADIATOR) Radiator 3.1 Memory Leak

[Forbes Mike]

We are using AuthBy PAM and using pam_krb5.so that came with Redhat Linux
2.4.18-3smp and radiator 3.1.

It works fine with a small amount of requests, but when we move our 900 or
so modems to the radius server it starts to take up in excess of 250 megs.
I assume this is not normal behavior or is it based on the number of
requests?

If this is indeed a PAM problem, what are my options (a custom auth mod)?
I need to authenticate via Kerberos and then a possible authorization with
LDAP.
