websphere 卡死问题

程序优化了很久，一开始以为是数据库连接池达到上限的问题，导致整个系统会被卡死3、4分钟，然后
又自动恢复正常，用的是websphere6.1最新版本。systemOut.txt中经常报出如下错误:

[08-2-18 9:25:13:421 CST] 0000020c SRTServletReq E SRVE0133E: 解析参数时发生错误。java.io.IOException: Async IO operation failed, reason: RC: 10054 远程主机易做图关闭了一个现有的连接。

不知是何原因，请高手们指点！！！ --------------------编程问答-------------------- 兄弟我也有个问题不知道你能不能帮帮忙，我的环境是Websphere6.1我出现在情况是我的系统进入后，有的部分页面整个页面都是乱码。

--------------------编程问答-------------------- 数据库连接池达到上限
这个是不可能的，如果可能是你的程序有问题！

WAS自带的有个性能监控，你看看！ --------------------编程问答-------------------- 不会,帮顶 --------------------编程问答-------------------- 没环境不知道如何解决，得看具体环境。
