[cvsnt] CVSNT Memory issues on 64-bit Suse Linux (AMD_64)

We've been using cvsnt compiled for 64bit-Suse 9 for about 3 months and
we are seeing some strange behavior in regards to memory de-allocation.
The system is configured to run out of xinet.d and is using ntlm_auth in
order to authenticate users against a domain controller.  Is there a
memory leak?  

Less and less system memory is available over the course of time.
Attached is an MRTG graph of the system.

We are seeing occasional segfaults in /var/log/messages which may be
related to this issue.  Perhaps the application is segfaulting before it
frees the memory.  However, we are only seeing about 1 segfault per 1000
connections to cvsnt.  

Has anyone else seen similar behavior?
