I will write about one problem. Although I understand that no one will answer here. Developers don’t care about users, but maybe who knows how to solve it? Sometimes clumsy data comes, maybe special characters or something else, and all this hangs like retain, and as soon as another client connects, it will be thrown out with the inscription “emqx maximum heap size reached”, I know for sure that this is because of broken data. But in which topic it is unclear. How do I find out which topic has broken data? logging doesn’t help!
I had the same problem, Did you solve it?
