								<td>To keep the number of expired session files under control, regular garbage collection is performed. The gc_probability is an integer between 0 and 100, indicating the chance that this process will start, where 0 = never, and 100 = always. The session driver executes this task as a shutdown event, to minimize the impact on the application.</td>
