Problem: Slow response time running commands on Dispatcher machine

If you are running the Dispatcher component for load balancing, it is possible to overload the computer with client traffic. The Load Balancer kernel module has the highest priority, and if it is constantly handling client packets, the rest of the system may become unresponsive. Running commands in user space may take a very long time to complete, or may never complete.

If this happens, you should begin to restructure your setup to avoid overloading the Load Balancer machine with traffic. Alternatives include spreading the load across several Load Balancer machines, or replacing the machine with a stronger and faster computer.

When trying to decide if the slow response time on the machine is due to high client traffic, consider whether this occurs during client peak traffic times. Misconfigured systems that cause routing loops can also cause the same symptoms. But before changing the Load Balancer setup, determine whether the symptoms may be due to high client load.
