In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a
configuration file, then sending a HUP signal to server triggers the
configuration to be reloaded from disk. If there are lots of clients
connected so that there are no more file descriptors/sockets available
(default limit typically 1024 file descriptors on Linux), then opening the
configuration file will fail.
