Parameter
Syntax
Example
2.3.1.38. nsslapd-conntablesize
This attribute sets the connection table size, which determines the total number of connections
supported by the server.
The server has to be restarted for changes to this attribute to go into effect.
Parameter
Entry DN
Valid Values
Default Value
Syntax
Example
Increase the value of this attribute if Directory Server is refusing connections because it is out of
connection slots. When this occurs, the Directory Server's error log file records the message Not
listening for new connections -- too many fds open.
A server restart is required for the change to take effect.
It may be necessary to increase the operating system limits for the number of open files and number
of open files per process, and it may be necessary to increase the ulimit for the number of open
files (ulimit -n) in the shell that starts the Directory Server. See
maxdescriptors (Maximum File Descriptors)"
2.3.1.39. nsslapd-counters
The nsslapd-counters attribute enables and disables Directory Server database and server
performance counters.
There can be a performance impact by keeping track of the larger counters. Turning off 64-bit integers
for counters can have a minimal improvement on performance, although it negatively affects long term
statistics tracking.
This parameter is enabled by default. To disable counters, stop the Directory Server, edit the
dse.ldif file directly, and restart the server.
