freeradius 1.1.4 stops answering (why?)

[Roberto S. G.]

hi,

I'm experiencing strange problems with a compiled freeradius 1.1.4 that
I have on a Reh Hat... I've used there other previous freeradius
versions without problem, but this one seems to maintain service for
just a couple of days, after which it stops authenticating. I had not
noticed this before, 'cause it was almost idle until now.
There's no strange error, even in "-X" mode.
Maybe it has something to be with connections to the ldap server...
freeradius makes connections to local stunnel ports, which then connects
to an Active Directory via ldaps (it has always run smoothly), but the
last configured freeradius ldap is a plain remote ldap connection just
in case stunnel stops running...
¿Maybe new FR versions has changes in the way it manages connections?.
The "Timed out while waiting for server to respond" error doesn't seem
to me correct, since a restart makes it dissapear, and I'd already risen
default values in radiusd.conf {ldap}:
                timeout = 60
                timelimit = 3
                net_timeout = 5
I just see in radius.log that there aren't more OK's (or KO's)...
I do not understand also the "Logout entry for NAS wireless-leon port 1
has wrong IDs" message... (I make no accounting).
[    I've tried also v1.1.6, but it's even worse: there're *much* more
"Logout entry for..." and "Error: rlm_ldap: ldap_search() failed: Timed
out..." and "Error: Discarding duplicate request..." logs, and others
related to NAS that didn't appear before; all with exactly the same conf
(which I compared line by line with 1.1.6 default one, without finding
new or deprecated attributes...), so I downgrade to 1.1.4 again...    ]
Any comment will be appreciated.
bye
