Hi,
         I have 2 ldap modules which are selected by unlang logic and I
have configured my certificates as default. Now when I put a dupticate
client entry in clients.conf file & then kill the radius server I got a
error like *** glibc detected *** radiusd: free(): invalid pointer:
0xb778e994. Also some time I get the error like munmap_chunk(): invalid
pointer. If I remove the duplicate client entry then I don't see the error.

radiusd -X .
