I then upgraded the master to 2.3.16 and now the sync_client segfaults immediately. I tried testing with plaintext allowed to no avail, after which I disabled TLS for the sync service (syncserver_tls_cert_file: disabled) with no improvement. The output from tcpdump indicates that the TCP session closes down immediately after the server sends the banner. I tried the patch supplied by Dietmar, which didn't fix the problem and in addition, rendered the master non-operational. I take it from the lack of followup on this thread, that this is not a problem experienced by the majority if any of the folks on this list. Has anyone else experienced anything like this? Any suggestions as to what might cause this before I dust off my debugging skills and attempt to trace the cause?
