tomcat下部署的oa应用，运行一段时间不能登录

部署的一个OA应用系统，windows安装版本tomcat7，JDK1.6

运行一段时间1-2个月，登录就会出现漫长的等待，不能登录，而点击其他不需要登录可以看到的信息则可以显示。
基本是用户出现超过10秒的登录不成功，就会把ie（白版）关闭。我这边接到通知，马上也是试一下，发现登录出现白板，就会重启tomcat。

日志信息我看了，本人找不到解决办法。请大家帮忙看看，附如下：

The diskStore path for this CacheManager will be set to D:\application\tlms\TlmsTomcat7\temp\ehcache_auto_created_1484202347913.
To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.
