6886N/A OpenDJ needs to be able to open many file descriptors,
6886N/A especially when handling thousands of client connections.
6886N/A Linux systems in particular often set a limit of 1024 per user,
6886N/A which is too low to handle many client connections to OpenDJ.
6886N/A When setting up OpenDJ for production use,
6886N/A make sure OpenDJ can use at least 64K (65536) file descriptors.
6886N/A For example when running OpenDJ as user <
literal>opendj</
literal>
6886N/A on a Linux system that uses
6886N/A you can set soft and hard limits by adding these lines to the file:
6886N/A <
programlisting language="none">opendj soft nofile 65536
6886N/Aopendj hard nofile 131072</
programlisting>
6886N/A The example above assumes the system has
6886N/A enough file descriptors available overall.
6886N/A You can check the Linux system overall maximum as follows.
