You have underlying problems with NSS, which means get*() libc calls are 
sporadically failing.

This is not a RADIUS problem; ensure your system can reliably make 
name/service resolution calls. If you are using nss_ldap, perhaps ensure 
it's not enabled for "services"; there's no value in doing these over 
the network.
