That's the only way we have to probe if a server is up; by creating a streaming connection and issuing an RPC. How else do you propose we contact a server? Those retransmissions that jhutz is talking about is for a single probe request. We can possibly run those probes in parallel, which is getting discussed a bit in another part of the thread, but that still involves going through this process. -- Andrew Deason adea...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
