Odyssey crashes under Ubuntu 20.04

When I have more than couple clients connecting to odyssey, it simply crashes. Here's a syslog information:

I'm using the latest master and also tried some earlier commits. I had no issues building from sources in dockers postgres image that runs on Debian.

Rough config I'm using:

daemonize no

unix_socket_dir "/var/run/postgresql"
unix_socket_mode "0644"

graceful_die_on_errors no
enable_online_restart no
