我遇到了一个 Web 应用程序的问题，该应用程序抛出 java.net.SocketException: Connection reset 异常。我相信抛出这个异常是因为客户端在从服务器发回响应之前关闭了连接。我无法在具有相同设置的开发环境中重新创建此问题。我重新启动tomcat后它工作正常，但应用程序在一段时间后开始抛出此异常。我怀疑我管理数据库连接池的方式，但正如我之前提到的那样，我无法重新创建这个问题。

以前的开发人员正在将日志写入控制台，这导致了一个非常大的 catalina.out 文件。我不确定这如何导致异常，但这是我看到的唯一奇怪的事情。以下是我的数据库配置。
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName.sqlserver}"/>
<property name="url" value="${jdbc.url.sqlserver}"/>

如果有人能对这个问题有所了解，我会很高兴，我正在使用 Spring 3.x、Hibernate、SQL Server、tomcat6。
