Hi All,

i'm configuring a new haproxy as a smtp and http/s proxy.
As a backend server i have 2 Kerio Connect email server.

all works good, but i have a strange behaviour of haproxy: after receive an email on port 25, haproxy dead.
This is when i start haproxy:
haproxy 17758 0.0 0.1 35192 1600 ? Ss 15:54 0:00 /usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -D -p /var/run/haproxy.pid
root 17808 0.0 0.0 10432 672 pts/0 S+ 15:54 0:00 grep --color=auto haproxy

This is after an email on port 25
root 17815 0.0 0.0 10432 672 pts/0 S+ 15:55 0:00 grep --color=auto haproxy

If i try to check the status with service haproxy status:
haproxy dead, but /var/run/haproxy.pid exists.

This is my haproxy conf

No error in haproxy.log or syslog.

Any idea ?

Thanks
