PS: If the payload more bigger (or bad network)，it would be raise more frequently

Apologies for the (very) delayed response. Can you please confirm if you are still seeing this and, if so, what version of the library you are using.

I'm going to close this as without more info there is little that can be done. It's possible that issue #853 has the same root cause (and there is some more info on that issue - have not traced a root cause at this point so any info you can add to that issue would be helpful).
