Setting the maximum number of open files (optional)

This section is not applicable to Windows. The system setting for the maximum number of open files prevents an uncontrolled process from taking over your system, but you might need a higher limit than the default if you are processing jobs with many files. Changing the open file limit lets your document processing feature use more system resources. This task is optional, but if File Not Found errors frequently appear in the job log during job processing, you should do this task.

To set the open file limit:

  1. Log in to your system as the root user, or use sudo or the su command to become the root user.
  2. On Linux: Open the file /etc/security/limits.conf.
  3. Find the line in the file that sets the open file limit. For example, on a Linux system it might look like this: aiw1 - nofile 4096.
    If the line does not exist, add it in the next step.
  4. Edit the line, or add a new line if needed, to set a higher limit for the RICOH ProcessDirector system user (aiw1 is the default).

    This example sets the limit to 15,000 on Linux: aiw1 - nofile 15000

    Check with your system administrator to determine a reasonable upper limit for the number of open files.

  5. Log out as root and log in to make the change take effect.
