您好，麻烦您找一下我，具体帮您远程看下。对应我的联系方式见左下角签名。

跟客户沟通对应该问题的产生原因为对应800个用户同时登录，每个用户登录时都要载入几个properties文件造成的。因为同时打开的properties文件数超过系统默认上限了。目前客户已经通过帖子：http://www.2cto.com/kf/201212/175863.html中的解决方案解决了问题。对应该问题开发人员已经在M3版本中优化了代码。客户对应是SP7。晚点我会将修改的文件和内容整理发给客户。

您好，附件是对应修正该问题的文件盒修改说明。请查收。如果对应问题解决了也麻烦在帖子上告知。

考虑到客户已经通过解决方案解决了该问题。同时提供的补丁文件也能解决问题，同时已经告知客户。对应帖子关闭。后续有问题再沟通。
