<p>
Configures the total number of mutexes to allocate. Berkeley DB allocates a default number of mutexes based on the initial configuration of
the database environment. That default calculation may be too small if the application
has an unusual need for mutexes. This parameter is used to specify an absolute number of
mutexes to allocate.
</p>
<p>
The syntax of this parameter in the <code class="literal">DB_CONFIG</code> file is
a single line with the string <code class="literal">mutex_set_max</code>,
one or more whitespace characters, and the total number of
mutexes. Because the DB_CONFIG file is read when the database environment is
opened, it will silently overrule configuration done before that time.
