-- Synchrony Database on non-windows OS not logging errors to log file
-- turning on extra logging for Synchrony database (all OS's)

Please add the following two lines to ..\Synchrony_Database\binaries\my.ini.
log_warnings=2
log-error

After a restart you should see a file in Synchrony_Database\binaries\data that is named <server name>.err

log-error   Optional on Windows systems. On Unix, errors go to console by default. Log-error is only needed to force logging to file on non Windows OS's.

log_warnings   will enable logging of warnings to the error log
log_warnings=2 will show warnings and aborted connections; note, disconnections will also happen normally when you stop Interchange.
