Hi
Did anyone using compiled version of haproxy on RHEL 7.x or derivatives? We have been running compiled version successfully last few years on RHEL 6.7 platform successfully. recently we migrated to RHEL 7.x, thus compiled using the same option which we are using on RHEL 7.x build system. i am having intermediate down every few days. Not seeing any relevent messages on logs ( /var/logs/messages or haproxy notiice logs) not sure why it is going down every few days and we have to issue reload to make it work again.
only noticeable difference is system-wrapper script and systemctl script. I am using system-wrapper generated from compiled version and using unit file from haproxy contribution directory.

any did one had similar experience? or any one using haproxy successfully on rhel platform using systemd based service management?
any help is highly appreciated. unable to breakthrough this issue due to insufficient log why it is failing every few days.
