tcp rst problem

My log collection system like  this:

fluent  => haproxy ==> rsyslog


In my case, haproxy will close the idle connection , 5 minutes after the last message . haproxy send FIN to fluentd actively , and fluentd  become close_wait , in this time, fluentd send a message,  haproxy will send RST immediately，after this  tcp connection is close.  The message you just sent is missing.
