I recently came across a notification in my Hivemq control center dashboard stating Qos 0 memory exceeded. Does this occur when a memory limit has been set previously has been exceeded? Also i read that new messages would get dropped. If that is the case how can i prevent the memory exceeded error and how can i prevent messages getting dropped?
Any answers are appreciated.
You previously asked about a different observed error, “Qos 0 channel not writable”:
For “Qos 0 memory exceeded” errors, everything @michael_w advised should still apply - it’s usually an issue of topic client subscriber consumption being a bottleneck. What was the outcome after reviewing his advice? Did you consider moving to a later version?
This is the Control Center analytics documentation for our current release if it could also be helpful:
