不允许在EventListener中调用ignite.queue和ignite.affinity方法，因为这可能导致死锁

所有缓存操作（包括EventListener）都在系统池中执行，因此不建议在EventListener操作内部调用，因为后者也使用系统池

您可以在“闭包执行和线程池”中阅读更多内容：

您是否在另一个线程中调用readFromQueue方法？是的，即使在另一个JVM中，您也只有2个节点？那么，您在这里说的“步骤2、3、4在不同的JVM中”是什么意思？日志中是否有任何挂起的事务、锁等？线程在其他节点上阻塞的位置？您可以共享线程转储和日志吗？对于数据，我有两个节点。我在不同的JVM中运行其他步骤。其中一个数据节点被卡住了。您可以很容易地尝试您自己的相同行为。您可以在ignite文档中显示您的解释。添加了答案链接
