<!-- STOP! If you are reporting a security issue, which includes *anything* that may cause the broker/client to crash, please do NOT report it here but follow the steps at https://www.eclipse.org/security/ If your issue is not a bug or a feature request, please use the mailing list at https://dev.eclipse.org/mailman/listinfo/mosquitto-dev to ask your question. There are many more people available to help there than on this issue tracker. If you are reporting a bug PLEASE include the version of Mosquitto you are using and what platform (Windows, Ubuntu/Fedora/... Linux, FreeBSD, ...) you are running on. Please also note that some systems have old versions of Mosquitto available in their package repositories. We would be very grateful if you would check to see whether the bug is still present in a newer version before submitting your issue. --> In Windows 10, there are more than 2300 clients, and new clients will not be able to connect
