急，我的程序运行10分钟tomcat就自动关闭了，帮帮小弟。
我的程序是在tomcat里面运行的，用的是struts1x，数据库连接方式为jdbc，数据库是access,程序功能是通过串口与硬件进行通信，将硬件返回的数据做处理并在web页面上显示出来。之前做的tomcat也会关闭但时间比较长，而这次的是隔十几分钟就tomcat就不行了。
以下是日志

[解决办法]
好像是你的java虚拟机出问题了，重装下试试。
[解决办法]
不太了解 把程序部署到其他的主机测试一下 是否楼主机器的环境哪里不对
jdk版本，tomcat版本等等
[解决办法]
你是不是用jdbc odbc桥的时候，从来没关连接啊
[解决办法]
反正尽量避免使用jdbc odbc桥，那个在多线程下，非常不牢靠
