Memory Issue on 3.0.25??

[Mucci Andrea]

Hi all,
we use FreeRADIUS Version 3.0.25, for host x86_64-redhat-linux-gnu. We use Oracle 19 and the client "ORACLE_HOME=/usr/include/oracle/19.12/client64".

In the last period we have this kind of issue:
Mon May 30 18:06:00 2022 : Error: Received conflicting packet from client eIUMRad port 51000 - ID: 153 due to unfinished request in module cache-clid.  Giving up on old request.

The process use a large amount of memory. With the version 3.0.18 we have never encountered this kind of issue.
