rlm_eap_tls: SSL_read failed in a system call

[Sean McNamara]

Hello all,
   
    I saw there was a bit of talk in 2006 over this issue, but, I wasn't 
able to track down a definitive solution.     We're running FreeRADIUS 
1.1.5 with EAP/TTLS (openSSL 0.9.8d) on Solaris 10.   The server will 
come up and process clients for a few days, but, every now and then it 
begins denying all auth-requests with the following error:

Apr 24 09:56:12 as2.villanova.edu radiusd[1033]: [ID 702911 
daemon.notice] Login incorrect (rlm_ldap: User not found): [anonymous]

daemon.error] rlm_eap_tls: SSL_read failed in a system call (-1), TLS 
session fails.

A restart makes the server happy and it goes back to properly auth'ing 
clients...

As of the moment I'm compiling FreeRADIUS 1.1.6 and hoping for some 
improvement, but, does anyone have any additional advice or experience 
with this issue.  .. or better yet, does anyone know the fix? 

Thanks for your time!

..Sean.
