[syslog-ng] new install of OSE 3.22 fails on ubuntu 16,04

Running on ubuntu 16.04 I have just compiled and installed syslog-ng version 3.22. When started it prints: iv_tls_user_register: called after iv_init and then exits. Google tells me there was a bug that caused this back in 2013 but there are not recent posts. Any idea what is going on? BTW I can’t use the binary packages as there are conflicts between the rsyslog and syslog-ng packages and I am stuck with having the rsyslog package by corporate policy. Russell
