Description
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.
Affected configurations
• eclipse mosquitto (>= 1.0 <= 1.4.14)
• debian debian linux 7.0
• debian debian linux 8.0
• debian debian linux 9.0
