Dan Berindei created ISPN-4459: ---------------------------------- Summary: Memory leak in HotRod client tests Key: ISPN-4459 URL: https://issues.jboss.org/browse/ISPN-4459 Project: Infinispan Issue Type: Bug Security Level: Public (Everyone can see) Components: Remote Querying, Test Suite - Server Affects Versions: 7.0.0.Alpha4 Reporter: Dan Berindei Assignee: Sanne Grinovero Fix For: 7.0.0.Final Even though the HotRod client stop their servers, each test instance keeps the reference to the servers it has started (both tests extending HotRodSingleNodeTest and those extending HotRodMultiNodeTest). In some tests, like the remote query tests, those servers' worker threads also keep references to huge thread-local {{io.netty.buffer.PoolThreadCache}}s (see attachment). Because of this, I'm sometimes seeing an OOM in the HotRod client suite. We should either clear the server references in the tests, or clear the worker threads when shutting down the server. -- This message was sent by Atlassian JIRA (v6.2.6#6264)
