On page 20, we found an error with the ArcMC installation. The following is defined as the values to set the limits.conf:
hard nofile 10240
soft nofile 10240
This causes the installation to fail. The correct limits.conf should read as:
* hard nofile 10240
* soft nofile 10240
Confirming with unlimit -n will allow the value to be set. Confirming the installation will succeed.
