nsslapd-maxdescriptors (Maximum File Descriptors)

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

the server as specified in the
non-client connections, such as index management and managing replication. See
"nsslapd-reservedescriptors (Reserved File Descriptors)," on page 74.
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

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:
