This message is generating by Sun’s resolver libraries and it is caused by incorrectly configured Domain Name Server(the server that the resolver libraries are querying not necessarly the local Domain Name Server). The Domain Name Server probably lacks a reverse map entry for that particular host. Since this “bug” is closely associated with using ypserv, Sun has produced a patch to “ypserv” (bug #1039839). Sun supplied a patch 100141-01 to quiet it, but the patched version appears to die silently at random times, so Sun now has a new patch, 100141-02. Do not install this patch unless you are really getting a lot of these messages.
