Question

我有一个抛出IOException的Java Web应用程序（Connection已关闭）。不幸的是，我无法找到问题的原因/来源（因此，我无法提供最小的代码示例）。我不能在开发环境中重现异常，在生产环境中它会被定期抛出（例如，50个登录用户：平均每10到20分钟抛出一次，有时更常见）。

如何确定此问题的原因（似乎它与使用的库有关，可能是某些配置问题）？

以下是设置：

使用Struts 2和JDBC（Postgres 9）的Java应用程序库：
- ASM-5.0.2.jar
- ASM-公地5.0.2.jar
- ASM-树5.0.2.jar
- 公地BeanUtils的-1.8.0.jar
- 公地集合-3.2.1.jar
- 公地消化器-2.0.jar
- 公地文件上传-1.3.1.jar
- 公地-IO-2.2.jar
- 公地琅2.4.jar
- 公地lang3-3.2.jar
- 共享记录-1.1.3.jar
- 的freemarker-2.3.22.jar
- 了Javassist-3.11.0.GA.jar
- javax.servlet-api.jar（3.1.0版）
- 的junit-4.7.jar
- OGNL-3.0.6.jar
- ojdbc14.jar的
- 的PostgreSQL-9.4-1201.jdbc41.jar
- struts2的核 - 2.3.24.1.jar
- struts2的瓷砖-插件-2.3.24.1.jar
- 瓦片-API-2.0.6.jar
- 瓦片核-2.0.6.jar
- 瓦片-JSP-2.0.6.jar
- XWork的核 - 2.3.24.1.jar
部署在Glassfish服务器4.1.1上

这是堆栈跟踪：
