Setting file limits for Linux

When running Alfresco on Red Hat Linux, if you encounter a "Too many open files" error message, you must increase the file limits setting.
These steps assumes that Alfresco is running as the alfresco user.
  1. Edit the following file:

    /etc/security/limits.conf

  2. Add the following settings:

    alfresco soft nofile 4096
    alfresco hard nofile 65536

    This sets the normal number of file handles available to the alfresco user to be 4096. This is known as the soft limit.

  3. As the alfresco user, set a system-level setting for Linux, up to the hard limit, using the following command:

    ulimit -n 8192
