Hi we are using
netty version : 4.1.29.Final
Maven dependencies are below
<dependency> <groupId>io.netty</groupId> <artifactId>netty-all</artifactId> <version>${netty.version}</version> </dependency> <dependency> <groupId>io.reactivex</groupId> <artifactId>rxnetty</artifactId> <version>0.4.20</version> </dependency> <dependency> <groupId>io.reactivex</groupId> <artifactId>rxnetty-servo</artifactId> <version>0.4.20</version> </dependency> <dependency> <groupId>io.reactivex</groupId> <artifactId>rxjava</artifactId> <version>1.3.8</version> </dependency> <dependency> <groupId>io.reactivex</groupId> <artifactId>rxjava-computation-expressions</artifactId> <version>0.21.0</version> </dependency>
Seeing the below exception.
Tried the below option '-Dio.netty.leakDetectionLevel=advanced' part of advice provided in
https://netty.io/wiki/reference-counted-objects.html
But that didnt help couldnt see which class in our project is causing the leak. May be the leak is in netty library itself? Please suggest on any solutions.
