Core Server Configuration Attributes Reference
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 72).
The number that you specify here should not be greater than the total number of
file descriptors that your operating system allows the
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. Note that the
Directory Server Installation Guide) can be used to 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

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.
