Then, reboot the Solaris machine to apply these changes.

2.2.4.2.4. File Descriptors

For a large deployment or to support a large number of concurrent connections, increase the
number of file descriptors available for the Directory Server. This requires accessing the system-wide
maximum file descriptor table. The governing parameter, rlim_fd_max, is in the /etc/system file.
By default, if this parameter is not present, the allowed maximum value is 1024. You can increase this
to 4096 by adding the line, set rlim_fd_max=4096 to the /etc/system file.
Reboot the Solaris machine to apply these changes.
To determine the soft limit for file descriptors, run the command ulimit -n. You can also use the
Section 2.2.1,
dsktune utility to determine the file descriptor hard and soft limits, as described in
"Using dsktune".
