            Bug ID: 244698
           Summary: NFSv3 lock manager unhelpful error message
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: wollman at FreeBSD.org

When the NFSv3 kernel lock manager times out trying to call back to a client,
it emits an unhelpful error message on the console:

NLM: failed to contact remote rpcbind, stat = 5, port = 28416

There are three things wrong with this message: the error is in decimal,
requiring users to read the source code to figure out which particular set of
error codes it's taken from never mind what it means; the port number is
byte-swapped; and most importantly, it does not identify the client the NLM is
trying to communicate with.
