Memory leaking when using ALPN #598
Description
We're experiencing a slow memory leak with 0.7.1 when using ALPN and TLS. The server is built and started with this code :
NettyServerBuilder builder = NettyServerBuilder.forPort(port);
definitions.forEach(builder::addService);
SslContext context = SslContextBuilder.forServer(keyCertPathprivateKeyPath).build();
builder.sslContext(context);
ServerImpl server = builder.build();
server.start();
This is the alpn version that we're using.
-Xbootclasspath/p:/usr/lib/java/alpn-boot-8.1.3.v20150130.jar"
Running a heap dump, we're seeing a huge amount of SSLEngineImpl objects stored in a concurrent hash map :
The server is running behind a Amazon ELB. This might be related since the Amazon load balancer would open connections every once in a while to the server and to ping and make sure the server is live. Unfortunately it takes a long time to replicate, the server would run out of memory after 36 hours or so, but it doesn't seem like the number of requests
