我尝试在 Websphere 8.5.5.9 的管理控制台中安装一个小型（4MB）war 文件，但安装失败，SystemErr.log 中出现以下堆栈跟踪：

我尝试过更改许多设置，包括超时值，但没有任何效果。它甚至在不同浏览器上的表现也不同。如果我在 Chrome 中打开控制台，它会在半个小时后才会失败。在 IE 中，它需要大约 2 分钟，但同样会失败。
其他人已经能够安装相同的 WAR，但我们无法找到可以解释它的差异。
还有其他人遇到过这种情况吗？
答案1
这实际上是一种解决方法，而不是答案，但我发现它与从“本地文件系统”选项安装有关。使用“远程文件系统”选项，即使 WAR 文件位于我的本地驱动器上，也可以工作。
