从WAS控制台 (6.1.0.31)，web服务器生成插件正常，传播插件失败，但是又不影响应用的使用，求解

生成插件：PLGC0005I: Plug-in configuration file = /WAS/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/was-1Cell01/nodes/IHS-1-node/servers/webserver1/plugin-cfg.xml

信息PLGC0052I: Plug-in configuration file generation is complete for the Web server was-1Cell01.IHS-1-node.webserver1.

传播插件失败
