I believe that dispatcher is the descriptive name you have assigned to one of the components of your load balancer configuration. This limit is controlled by the maximum file handles for the user running haproxy. You should increase the limit on the number of file handles per user. This is probably controlled by the file /etc/security/limits.conf, though it may depend on your distribution. To achieve 5000 you should set the file handles to something in the neighbourhood of 11000. Additional tuning may be required to support this level of simultaneous connections, especially if each one is short lived. You can check the mailing list archives for discussion on the subject. -JohnF
