Issue
There is slow performance during heavy load (such as large reviews involving 1000+ reviewers) and severe system lag including the login page failing to fully load with only 50-75 simultaneous connections

The xinetd.log (usually located under /var/log directory) shows the following error: 
 
FAIL: https service_limit from=<server IP address>
Cause
Red Hat documentation on TCP Wrappers and xinetd indicates that the instances entry sets the maximum number of requests xinetd can handle at once.  By default the L&G appliance is set to use the default number of instances, which is 30.

When the number of instances of the TCP wrapper is maxed out, the system would experience slowness/contention on the UI with the higher number of simultaneous connections.
 

 

 

Resolution
Increase the number of instances in the /etc/xinetd.conf, by doubling or more the instances value.
