By default, or if the value is set to 0, the default size is
approximately 60KB. The log region is used to store filenames, and
so may need to be increased in size if a large number of files are
opened and registered with the specified Berkeley DB
environment's log manager.
</p>
<p>
If the database environment already exists when
<a href="M_BerkeleyDB_DatabaseEnvironment_Open.htm">Open(String, DatabaseEnvironmentConfig)</a> is called, the value of
RegionSize is ignored.
