Maximum number of simultaneous connections
Maximum connections (pre_spawn)
Specifies the maximum number of simultaneous connections from clients. The specified
number of processes listen for connections from clients.
You can check the number of connections used in "Internal process ID" in the access log
(access.log).
￭ If you increase the value of this setting, the number of simultaneous connections is
increased, but it requires more memory. Approximately 500 KB of memory is used per
process.
￭ A warning is output to the error log if the maximum number of connections is reached.
￭ We recommend that you set an initial value of approximately 50 and then monitor the
performance. The setting is usually set to a value of less than 200. (The setting itself
permits values up to 9999.) )

DNS Reverse Lookup (reverselookup)

specify the [Access control]=[From these hosts] settings. The host name of the accessing host
is also shown in the access log.
