FR failing

We have two FR servers (running 1.1.15) on Red Hat machines.

We are using it to authenticate wireless users against an LDAP directory. Occasionally, one of the FR servers (it happens to each, just not at the same time), stops working. The service remains up, but it’s like the conversation between radius and ldap doesn’t work for some reason, and radius stops trying altogether afterwards. The log shows:

Thu May 1 14:33:02 2008 : Error: rlm_eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request

Any help is greatly appreciated.

Thanks
