Interesting, I’ve not seen this before. ~~Do you think it’s worth splitting this out into a separate thread since this is another issue to the original issue of this thread?~~ Done.

Could you post output of `$sudo top` to show the memory use of `mqtt_service`?

What happened in the last few days, did the memory use continue to increase? Did the system crash?

Is @Pukka running a stock emonSD setup? Have there been any changes made?

What version of Mosquitto, Redis and Emoncms and Emonhub is @Pukka running
