nsslapd-reservedescriptors (Reserved File Descriptors)

Not applicable to Directory Server installations on Windows and AIX machines.
This read-only attribute specifies the number of file descriptors that Directory
Server reserves for managing non-client connections, such as index management
and managing replication. The number of file descriptors that the server reserves
for this purpose subtracts from the total number of file descriptors available for
servicing LDAP client connections [see "nsslapd-maxdescriptors (Maximum File
Descriptors)," on page 70].
Most installations of Directory Server should never need to change this attribute.
However, consider increasing the value on this attribute if all of the following are
true:
• The server is replicating to a large number of consumer servers (more than 10),
and/or the server is maintaining a large number of index files (more than 30).
• The server is servicing a large number of LDAP connections.
• You are seeing error messages reporting that the server is unable to open file
descriptors (the actual error message will differ depending on the operation
that the server is attempting to perform), but these error messages are NOT
related to managing client LDAP connections.
