(RADIATOR) Radiator hanging on LDAP

[Chris Hills]

Hi

We are using Radiator mainly to authenticate wireless users with 802.1x
and EAP-PEAP with an LDAP backend. Recently I have noticed that on
occassion the server gets "stuck" and no longer processes
authentications until radiusd is restarted. The log file shows dozens of
binding messages every second, for example:-

Any idea on what could be happening?

P.S. I emailed OSC a couple of weeks ago to get a quote to extend our
now expired support contract and have heard nothing since.
