So this basically partially overrides what this commit has done (wrong):

commit f1271380381bb49b4a4c38950fe77a60d19ea9a3

    rpc: Report proper close reason
    
    Whenever client socket was marked as closed for some reason, it could've
    been changed when really closing the connection.  With this patch the
    proper reason is kept since the first time it's marked as closed.

Without the mentioned commit the last error would be remembered. It is
probable that in some cases the error would be overwritten incorrectly
so I think that the combination of these two patches should do the
trick.

ACK
