Running mosquitto mqtt broker on a vps and it keeps crashing when i have more than 50 clients connected. Each client publishes data every 5 seconds. Server has 2gb ram which should be plenty right? Getting really frustrated with this, any suggestions?

2gb should definately be enough for 50 clients. Check your mosquitto logs for any errors. Also look at your persistence settings - if you have QoS 1 or 2 messages with persistence enabled, that could cause issues. Try increasing max_connections in mosquitto.conf. Another thing to check is if you're using websockets, those can be more resource intensive than regular mqtt. What version of mosquitto are you running?
