Question

我是支持WAS（Websphere Application Server）的新手，目前我遇到了WAS问题，我的WAS安装在AIX下2台服务器/节点下。在调查时，我在应用程序日志中发现有一些活动是＆＃34;执行缓存维护＆＃34;：

===================================

===================================

在此活动触发后，我发现mpmstats值为＆＃39; bsy＆＃39;不断增加，直到达到MaxClient最大值，即＆＃39; 4000＆＃39;：

===================================

在达到最大值之前，WAS似乎没有处理客户端请求。

问题是：

是否有任何日志可以检查为什么WAS在达到最大值之前没有处理客户请求？
＆＃34;缓存维护＆＃34;活动是否阻止WAS处理客户请求？因为正如我们的开发人员所提到的，此活动不应导致此问题。
我可以采取哪些程序来识别/解决此问题？

感谢能否帮助我解决这个问题，因为这个问题已经发生了很长时间但仍未解决。

没有处理请求，因此无法使用Web
