Netscape DIRECTORY SERVER 6.01 Configuration Manual page 59

This attribute sets the maximum, platform-dependent number of file descriptors
that the Directory Server will try to use. A file descriptor is used whenever a client
connects to the server, and for some server activities such as index maintenance.
The number of available file descriptors for TCP/IP connections is the total for the
nsslapd-maxdescriptors
the server as specified in the
non-client connections, such as index management and managing replication. (see
"nsslapd-reservedescriptors (Reserved File Descriptors)" on page 63).
The number that you specify here should not be greater than the total number of
file descriptors that your operating system allows the ns-slapd process to use. This
number will differ depending on your operating system. Some operating systems
allow you to configure the number of file descriptors available to a process. See
your operating system documentation for details on file descriptor limits and
configuration. It is worth noting that the included
suggest changes to the system kernel or TCP/IP tuning attributes, including
increasing the number of file descriptors if necessary. You should consider
increasing the value on this attribute if the Directory Server is refusing connections
because it is out of file descriptors. When this occurs, the following message is
written to the Directory Server's error log file:
Not listening for new connections -- too many fds open
NOTE UNIX shells usually have configurable limits on the number of file
descriptors. See your operating system documentation for further
information regarding limit and ulimit as these limits can often
cause problems.
