Failed to drop supplementary groups.

[f1-outsourcing]

When I add to a working config these lines, and restart haproxy ( haproxy -W -db -f /usr/local/etc/haproxy/haproxy.cfg)

program api
    no option start-on-reload
    command /usr/local/bin/dataplaneapi --host 0.0.0.0 --port 5555 --haproxy-bin '/usr/local/sbin/haproxy' --config-file $HAPROXY_CFG --reload-cmd '' --reload-delay 5 --userlist controller

I am getting these errors

Hi, @f1-outsourcing

this does not seem to be related to config-parser.
This is related to haproxy itself.
Please report this issue on haproxy mailing list or on haproxy github page github.com/haproxy/haproxy/
