Random lost of notice of broadcast result

[pluswave]

In some rare case, notice of broadcast (broadcast_transaction_with_callbac
k) result never happens.Here is the rpc log in the server:

2017-11-17T02:11:33                th_a:?           operator() ] "server": server msg->get_payload(): {"method":"call","params":[3,"broadcast_transaction_with_callbac

I can't find a related 5505 notice in the log file.

more info: the broadcast failed in the end, but the client (bitsharesjs /bitsharesjs-ws) never know this because of lost notification.

steemit/steem@0fb4057 is related.

Actually, should check steemit/steem#592, however, the code is a bit old, I'm not sure if it will work without additional issue.
