   Hi, this is the problem of my custom plugin.
   Can I ask what tools can I use to find out which exactly code cause this memory leak?

   What's the RSS value of this worker?  VSZ is the total mapped memory account.
   
   BTW, What's the configuration of APISIX, and how did you configure APISIX (Routes, Upstreams, and so on)?
