Your tcpdump.log shows that walsender doesn't send any invalid messages,
but walreceiver seems to receive it. So, I suspect libpq functions which
walreceiver uses as the cause of the trouble. I changed synch-rep to dump
all the behaviors of those libpq functions.
Please retry new synch-rep code and report the following information.
* server log
* <installation_directory>/sbydata/walreceiver_trace.out
* tcpdump -i lo -n tcp
