我将Spring-JMS DefaultMessageListenerContainer实现更改为使用CACHE_NONE的cacheLevelName并遇到以下异常。概述了here。我正在使用glassfish v 2.1，Open MQ 4.4和Spring 3. *。关于我可能出错的任何想法？

此C4000错误是网络通用异常处理程序。这可能是缓存级别更改的结果。应用程序可能会打开太多与服务器的连接，具体取决于您的池设置，并且服务器可能缺乏管理它们的资源 - 最好的猜测可能是内存。
请检查您的OpenMQ服务器日志文件和内存使用情况。
消费者和MQ服务器之间是否有可以控制连接建立的网络配置（防火墙，QoS路由器......）？很快打开许多连接可能被视为SYN泛洪，这是一种常见的DoS攻击。
