[Tong-07]

Expected behavior

Actual behavior

Steps to reproduce

Minimal yet complete reproducer code (or URL to code) or complete log file

Moquette MQTT version

MQTT_3_1_1

JVM version (e.g. java -version)

1.8

OS version (e.g. uname -a)

centos 7
More than 10,000 clients are connected, usually once every week, the connection will not be connected, some data cannot be sent down, and some will also appear after internalPublish, empty pointer error, and no stack information.
After the restart, it will return to normal. How to troubleshoot this?

@Tong-07 your description is not enough to reproduce or investigate the issue.

Please provide a reproducer or some useful logs when the issue manifest. However, I would check the memory status of the JVM process, in particular the direct memory, used by the network stack (MQTT Netty codecs).
