+The maximum number of variables in a system can be tuned through
+the \b maxmin/concurrency_limit item (default value: 100). Setting a higher value can lift some limitations, such as the number of concurrent processes running on a single host.

+storage/max_file_descriptors item to either enlarge it if your
+application requires it or to reduce it to save memory space.
