I try retrive subscriptionStore.iterateAllSubscriptions but catch exception with null on server with one cpu. But server with four cpu's all good. Can i turn some java/hivemq options for normaly run on 1 cpu ?

Hi @alexworkgit - to be sure could you post the stack trace of the exception? I'll pull in the team to take a look.

No output exception of server, blocking function subscriptionStore.iterateAllSubscriptions simply freeze or non blocking wraped in my try block return exception with null message.

Maybe simple add error for 4 cpu and stop start of daemon ?

Unfortunately not per the minimum hardware requirements.

If you need to run a broker on smaller or even embedded hardware, HiveMQ Edge has a much smaller footprint. It's purpose varies somewhat but it might be of use depending on your setup:

HiveMQ Edge is an MQTT broker, MQTT-SN gateway and modular industrial protocol converter that is designed to run on constrained/embedded hardware.
