   @pguokun 我在腾讯云TKE（K8S）也发现有这个问题，内存增长趋于线性，我们这边用的插件如下：
   
   全局插件：
   - request-id
   - resonset-rewrite
   - kafka-logger
   
   路由插件：
   - proxy-rewrite （5%）
   - consumer-restriction （70%）
   - hmac（70%）
   - limit-count (70%)

   不太清楚这里面有没有GC机制，如果有GC，GC的触发条件是不是内存占用到一定程度时才触发？而运行在容器里面，程序看到的内存其实是宿主机的内存，而非容器limit内存，会导致永远不可能触发GC呢？目前Python3.7及以下版本就有这个问题，看到的是宿主机的资源，导致GC不会被主动执行。
   
   以上，仅供参考哈~
