jgroupsを介して配布するehcacheを使用します。配布にはUDPmulticatを使用しています。

ehcacheはwebapp内にあります。そのWebアプリケーションを実行するマシンがいくつかあります。どういうわけか私は警告NAKACKを取得します。ehcacheのいくつかのインスタンスがjgroupに参加できないようです。

これはehcache構成（jgroups-configを含む）です：

<cacheManagerPeerProviderFactory        class="net.sf.ehcache.distribution.jgroups.JGroupsCacheManagerPeerProviderFactory"
    properties="connect=UDP(mcast_addr=${ehcache.multicast.address};mcast_port=45566;ip_ttl=32;
        mcast_send_buf_size=150000;mcast_recv_buf_size=80000):
        PING(timeout=2000;num_initial_members=6):
        MERGE2(min_interval=5000;max_interval=10000):
        FD_SOCK:VERIFY_SUSPECT(timeout=1500):
        pbcast.NAKACK(gc_lag=10;retransmit_timeout=3000):
        UNICAST(timeout=5000):
        pbcast.STABLE(desired_avg_gossip=20000):
        FRAG:
        pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;
        shun=false;print_local_addr=true)"
    propertySeparator="::" />

これはスタックトレースです。

これについて私ができることはありますか？ありがとう

とにかく、あなたの投稿は半年前です。そのような場合、サーバーが同じ物理ネットワークにあり、udp 通信に使用するポートがそれらの間のどこにもブロックされていないことを確認する必要があります。
