XDMCP service crashed

[Gus Fritschie]

I was scanning a Unix System V Release 4/MP-RAS NCR box with Nessus.  I was 
alerted that the file system was filling up due to this error message that 
kept repeating.  Here is a portion of the log:

error (pid 5943): Cannot convert Internet address 192.x.x.x to host name
_XSERVTransTLIAccept() t_listen() failed
_XSERVTransTLIAccept: An event requires attention
_XSERVTransTLIAccept() t_listen() failed

_XSERVTransTLIAccept() t_listen() failed

I believe the Nessu plugin that caused this was 
http://cgi.nessus.org/plugins/dump.php3?id=10891

Any ideas on why this occured.  Thanks!
