MQTT Client sessions total

Hi @michael_w

Thanks for the reply.
I’ve figured the cause of the problem, which was (as I assumed) our issue, where some clients were connecting with random IDs without clean sessions and causing the slots to be filled up.
However, as these random IDs have not been used again, I would expect them to be purged from the cluster after 3 days, but the count is not going down and still stuck at 100.

I need to decide by this week as we need to move into a Pay-as-you-go account to start actively using their service in a production project.
Does it really clean up at 3 days or monthly or never?
Monthly would make sense, to match a paid account’s billing cycle. Getting stuck forever would be a major drawback.

Can anyone from HiveMQ help with this question?
