Setting open files for FAS

If you have installed FAS on a Linux-based operating system, such as CentOS, you may need to configure the ulimit settings on the server to enable it to handle the number of clients in your installation. If the ulimit setting is set too low, you will see the following error:

Too many open files

The Media Broker also requires other file handles in addition to those for client connections, so you need to over-provision. For example, if your installation would include 5000 connections you should set the maximum number of open files to 7000.

1. To see the current maximum number of open files, log on to the Web Gateway server and run the following command:

ulimit -n

2. To change the number of open files, open /etc/security/limits.conf and search for the following line:

* - nofile 1024

Note: In some installs this line will not exist and the value will default to 1024. In this case a new line will need to be added.

3 Change 1024 to the setting you require, in the above example that would be 7000:

* - nofile 7000

4 To confirm that the setting has changed, log out and log back in again before running the above command to check the maximum number of open files.

ulimit -n (should return 7000)
