Calls to GsSocket>>getHostNameByAddress: can hang indefinitely.
This is caused when a partially-qualified address argument is passed to getHostNameByAddress:, and the underlying code executes a getnameinfo call to the DNS name server, which responds with an EAI_AGAIN error (see the man page for getnameinfo for details). GemStone keeps repeating the operation, hoping to get a correct response, which never comes.
Investigate the configuration of your DNS name server in terms of this address argument to determine the root cause.
