JBOSS all thread are curently busy,waiting connection reset

 最近系统出现了几次问题，报错如下。

在请教各位大拿和google/baidu以后，大概整理了一下可能的解决方案：

1，在oracle-ds.xml的数据源配置中添加<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>

2，Apache通过mod_jk1.2 转发http 请求给jboss，修改 jboss-4.0.5.GA/server/default/deploy/server.xml调整ajp connector 设置：<Connector port="8009" address="${jboss.bind.address}" backlog="1200" maxThreads="2100" minSpareThreads="20" maxSpareThreads="50" emptySessionPath="true" enableLookups="false" redirectPort="8443" protocol="AJP/1.3"/>，同时在linux  的.bash_profile  增加文件句柄:  ulimit  -n  4096。

3，怀疑是网络的问题，尤其应用服务器与数据库服务器之间的连接问题，让IDC换了一根网线，还有可能就是内部LSB的问题（目前没做调整）。

具体效果待验证，如果有遇到类似问题的，希望能提供更为确定的解决方案，将非常感谢。

自从换了网线后就没出过问题。。。。

也许真的是网络的问题。。。。MD
