Andrey Mashenkov updated IGNITE-15398:
--------------------------------------
Description:
I've run a simple test and face OOM on 7 of 100 iterations.
Seems, thread leakage is a reason.
Use JVM arg `-Xmx512M` to run the test, otherwise more iterations may be
required.
{code:java}
@RepeatedTest(100)
public void nodeRestart100Test() throws Exception {
List<Ignite> grid = startGrid();
IgniteUtils.closeAll(Lists.reverse(grid));
}
{code}
Thread dump shows a huge number of parked NioEventLoopGroup and
JRaft-Request-Processor.
Further investigation shows most of NioEventLoopGroup threads are acceptor
threads created in startEndpoint() method of RestModule and ClientModule
classes.
