The value of the parameter (a decimal integer) represents the
number of
minutes of inactivity before a connection is considered dead, and it is
disconnected. The deadtime only takes effect if the number of open
files is zero.
This is useful to stop a server's resources being exhausted by a
large number of inactive connections.
Most clients have an auto-reconnect feature when a connection is
broken so in most cases this parameter should be transparent to users.
Using this parameter with a timeout of a few minutes is
recommended for most systems.
A deadtime of zero indicates that no auto-disconnection should
be performed.
Default: deadtime = 0
Example: deadtime = 15
