This one has almost a minute different timing - are you sure these are
related? Try adding the pid field to log_line_prefix (%p) to make
sure.

That means "connection refused", which would indicate that the
*client* dropped the connection. Is the only thing you changed going
from 8.3 to 8.4? Or did you also upgrade something else on the system?

Do you use SSL for your connections?

Can you also try the latest 8.3 (8.3.7) to see if some backported fix
caused this?

And the usual question always applies - any firewall or antivirus on the server?
