Examples with TcpServer com.hazelcast.internal.server.tcp.TcpServer used on opensource projects

Example 1 with TcpServer

use of com.hazelcast.internal.server.tcp.TcpServer in project hazelcast by hazelcast.

the class NioChannelMemoryLeakTest method assertNoChannelLeak.

private void assertNoChannelLeak(HazelcastInstance instance) {
    int clusterSize = instance.getCluster().getMembers().size();
    // There may be one or two channels between two members.
    // Ideally there'll be only a single channel,
    // but when two members initiate the connection concurrently,
    // it may end up with two different connections between them.
    int maxChannelCount = (clusterSize - 1) * 2;
    TcpServer networkingService = (TcpServer) getNode(instance).getServer();
    NioNetworking networking = (NioNetworking) networkingService.getNetworking();
    Set<NioChannel> channels = networking.getChannels();
    assertThat(channels.size(), lessThanOrEqualTo(maxChannelCount));
    for (NioChannel channel : channels) {
        assertTrue("Channel " + channel + " was found closed (channel: " + channel.isClosed() + ", socketChannel: " + !channel.socketChannel().isOpen() + ") in instance " + instance, !channel.isClosed() && channel.socketChannel().isOpen());
