wangdafang opened a new issue #4630: [Significant BUG]Spring Annotation Plugins Makes FULLGC Without Stop URL: https://github.com/apache/skywalking/issues/4630 Environment: 19 agents 1 skywalking-oap-service-6.6.0 1 es-6.6.2. sw-oap-jvm-param: jvm-param -Xmx12g，-Xms12g，-Xmn6，-XX:SurvivorRatio=8 Desc: 19 agents with optional-spring-plugins - spring-annotional-plugins. When the skywalking-opa-servic begins running,this will happen： the jvm-Eden increasing，this will lead to the jvm-OLD increases.When the jvm-OLD is used by 100%,the process will try fgc for all the time,and will provide no service for agent and ui. At this time,the skywalking-opa-service process is exit,but there is no service provided. I have found,that when the operateID is null,sw will try save the objs into buffer-file.But when the flows become upper and upper,the excessive objs should be given up. It bothers me a lot,and I need help
