Memory leak in Websocket implementation (8.1.0 Final) ----------------------------------------------------- Key: WFLY-3976 URL: https://issues.jboss.org/browse/WFLY-3976 Project: WildFly Issue Type: Bug Components: Web Sockets Affects Versions: 8.1.0.Final Environment: CentOS 7 Java 1.7.0_65-b17 Reporter: Veli Cris Assignee: Stuart Douglas Priority: Critical Fix For: 8.2.0.Final Creating 100k persistent websockets connections, exchanging small strings (with RemoteEndpoint.Basic) and finally disconnecting all connections the memory grows with ~1GB for each 100k. Basically the test is the following: the clients are connecting and sending a hello message to the server; the server is responding with a welcome string and the clients are disconnecting. The settings in onOpen() callback are: session.setMaxBinaryMessageBufferSize(10240); session.setMaxTextMessageBufferSize(10240); session.setMaxIdleTimeout(120000); session.getUserProperties().put("ts", System.currentTimeMillis());
