我们在安装 wso2 esb 时遇到了问题。
我们只配置了 4 个代理服务，一个月后没有问题，我们开始出现以下错误：
2013-10-02 09:29:09,366 [-] [PassThroughHTTPSListener] WARN PassThroughHttpSSLListener System may be unstable: HTTPS ListeningIOReactor encountered a checked exception : Too many open files

如果我列出 java 打开的文件列表，我会看到数百个：
java 3906 root 150u sock 0,7 0t0 9928 can't identify protocol
java 3906 root 151u sock 0,7 0t0 10004 can't identify protocol
有人可以指出这个错误的原因吗？
谢谢你。
