StreamOutput stopped: can't get record: can't unmarshal record: proto: illegal wireType 6 ?

[wangfeiping]

I run hekad on a lot of server, but just one server show error log and shut down.
All the server is same, same system, same path, same config.
I don't know why, every time I restart hekad then the server will show me the log!
