LDAP authenticiation stops working after a while

[VM]

Hi everyone,

I have a queer comportment on a Debian FreeRadius version

The server is configured to authenticate the users (with a bind) on two
identical LDAP servers through SSL.
(for 802.1x authentication purposes)

This works quite fine for a while (a few days) and then stops working at all untill service restart.

Should this be related to a machine limitation ?
A buffer overflow or so ?

At the time the service stops working, about 30 LDAPS connexions are open between FreeRadius
and the first LDAP server (the second one in never sollicitated)

Is there a way to limit the LDAP connexions' duration and force FreeRadius to close them after this limit
and open new ones (to clean its buffers) ?


Any help will be appreciated.


The auth mechanisms used are EAP-TTLS + PAP with SecureW2 supplicant.

Best regards
