@zimmerle How to solve this problem?　The impact of this problem is very serious. I hope that the government will pay close attention to the repair and repair version 3.0.4 as soon as possible

@Hello-Linux copy in paste the same comments across multiple issues is not good for the project index. Please avoid doing it.

Typically, users search for the existing issues before opening a new topic. Sometimes they get a response by just reading a similar problem.

I also encountered the same problem. It is the same with the latest 3.0.7. After nginx - s reload, there is a lot of memory leakage, and the memory is basically consumed after several more executions. This problem is very serious and has a great impact on the production environment
