在线急等weblogic集群关于proxy的问题，急急急急

有那位大哥对weblogic的集群比较了解，能救小弟一吧么？
我们的系统在hp-8000小型机上运行，用weblogic7，和oracle.配置了weblogic的集群，有一个adminserver,4个managedserver,用HttpClusterServlet做代理，server class是weblogic.servlet.proxy.HttpClusterServlet,昨天晚上部署了新程序，今天早上突然系统非常不稳定，从weblogic的控制台上看都运行的比较正常，但是系统登陆就是一个白屏，重起weblogic一段时间效果不好，在看webligic console log 的时候发现启动的时候抛出异常，由于log没有保存下来，大概就是说proxy出了一些问题，导致使得几个managedserver的端口被shoudown了，然后又几次重起webligic虽然不出那个log但是系统及其不稳定，很快就不能登陆了。以前系统是比较稳定的，一办都很多天都不用重起weblogic,除非是部署新的ear。希望有人能帮助我解决以下回贴qq都可以，晚上不休息，在线等，谢了。小弟qq6642783

不过后来在没有出现这种log但是出现的问题我感觉还是和这个有关系
小弟的qq一直隐身在线等，谢了

前面的log没有发清楚再次补上

说不定我可能解决!
