Version 1

    We are using httpd (Apache/2.2.15) + mod_cluster/1.2.11.Final + 5 JBoss EAP 6.4.5 nodes using the AJP connector to the nodes.  I am getting CLOSE_WAITs from apache to the nodes/instances on port 8009 which aren't closing/releasing.  There doesn't appear to be any issue on each of the individual JBoss instances with any open connections.. just an accumulation on the balancer.  It appears we hit maxclients (3000) and the balancer can no longer handle requests, restarting httpd releases all the connections but booting users or restarting the service isn't a solution.

     

    Thanks,
