memory leak while using brave library from Spring cloud sleuth
siganapathy opened this issue · 3 comments
Describe the bug
We use spring cloud sleuth library for tracing in our application. We deploy our application on kubernetes. We have observed that long running pods (more than 10 days) experience High CPU usage (around 300-350%). GC threads get stuck spending (90% CPU). When we took heap dump, we observed this class brave.baggage.CorrelationUpdateScope$Single taking up 55% of size. looks like there is a memory leak and it is not getting garbage collected properly. This class belongs to the brave library which comes from the spring-cloud-sleuth-brave library which is a transitive dependency coming from parent spring-cloud-starter-sleuth dependency. Can someone share some insights on this ?
