我在Lifecat 6上安装了一个问题，在Tomcat 7上运行：昨天它的cpu使用量飙升到100％，并开始记录几个异常;查看线程转储显示两个gc线程（gc任务线程＃0（并行gc））负责此高CPU使用率。
我重启tomcat几次，但每次使用gc线程再次回到100％cpu时，记录大量异常。这些例外情况涉及范围非常广泛，并且被Liferay核心课程抛出，我不明白为什么。一些例外引用了Lucene，我已经尝试通过portal-ext禁用索引，但没有效果。
一些例子：

我也有几次这样的行：
PortalException: No JournalArticle exists with the key {groupId=10184, articleId=/1832648, status=-1}
更新
最后，我们通过将Lucene索引设置为只读（将index.read.only=true置于portal-ext.properties），删除每个portlet并一次重新启用它们，设法让Liferay重新启动并再次运行。几天后，我们再次在写入模式下启用了索引。但是我们发现索引中存在一些不一致之处，我们可能会重新生成它们。
答案 0 :(得分：1)
这两个例外：
11:34:01,607 ERROR [RuntimePageImpl-3][IncludeTag:129] Current URL null generates exception: null
和
java.lang.IllegalStateException: Page needs a session and none is available
是因为您打开旧会话（在重启服务器之前）。
stacktrace
freemarker.template.TemplateModelException: Method public java.lang.String com.liferay.portlet.assetpublisher.util.AssetPublisherHelperImpl.getAssetViewURL(com.liferay.portal.kernel.portlet.LiferayPortletRequest,com.liferay.portal.kernel.portlet.LiferayPortletResponse,com.liferay.portlet.asset.model.AssetEntry) threw an exception when invoked on com.liferay.portlet.assetpublisher.util.AssetPublisherHelperImpl@3fca83b9
和
PortalException: No JournalArticle exists with the key {groupId=10184, articleId=/1832648, status=-1}
已关联。如果认为你的freemarker例外是因为Liferay找不到你的JournalArticle。
最后，我认为找不到你的JournalArticle，因为你的lucene索引有问题。
您可以删除lucene索引并重新启动完整索引吗？
