max open files.
To set a different value than the default one, uncomment, and configure this
setting. Remember that this value CANNOT be higher than the hard limit. Raising
the hard limit depends on the OS and/or distribution, a good way to find the
limit is to search the internet for something like this:

Worker threads should not be put below 3 when using the peer system, but can
drop down to 1 worker otherwise.
.. note::
When the master daemon starts, it is expected behaviour to see
multiple salt-master processes, even if 'worker_threads' is set to '1'. At
a minimum, a controlling process will start along with a Publisher, an
EventPublisher, and a number of MWorker processes will be started. The

------------------------------------------------------
These two ZeroMQ High Water Mark settings, ``salt_event_pub_hwm`` and
``event_publisher_pub_hwm`` are significant for masters with thousands of
minions. When these are insufficiently high it will manifest in random
responses missing in the CLI and even missing from the job cache. Masters
that have fast CPUs and many cores with appropriate ``worker_threads``
will not need these set as high.
The ZeroMQ high-water-mark for the ``SaltEvent`` pub socket default is:
.. code-block:: yaml
salt_event_pub_hwm: 20000
The ZeroMQ high-water-mark for the ``EventPublisher`` pub socket default is:
