Set the Limit on the Number of Open Files on Data Collector

Verify that the user that is installing the Data Collector has a value of at least 65536 on the number of open files. Set this value permanently.

Follow these steps:

As the root user or a sudo user, log in to the computer where you are going to install the Data Collector. Open a command prompt and type the following command to change the ulimit for the open files limit to at least 65536:
```
ulimit -n ulimit_number
```
For example:
```
ulimit -n 65536
```
Open the /etc/security/limits.conf file on the computer where you are going to install the Data Collector and add the following lines:
```
# Added by Data Collector
* soft nofile 65536
# Added by Data Collector
* hard nofile 65536
```
Note: Restart the Data Collector for these changes to take effect. If you are upgrading, the upgrade process automatically restarts the Data Collector.
To verify that the number of open files is set properly on the computer where you are going to install the Data Collector, type the following command:
```
ulimit -n
```
The command returns the ulimit number that you specified earlier.
