我在EC2上的Ubuntu 14.04上有一个Jenkins服务器。 最近，页面的加载时间已经痛苦地恶化。
当我查看日志时，我注意到在构build完成之后，Jenkins不能删除像lastUnsuccessfulBuild和lastStableBuild这样的快捷方式的链接：

/var/lib/jenkins/jobs/tests_functional上的文件所有权似乎是正确的：
drwxr-xr-x 2 jenkins nogroup 4.0K Apr 8 20:53 lastSuccessful drwxr-xr-x 2 jenkins nogroup 4.0K Apr 8 20:53 lastStable -rw-r--r-- 1 jenkins nogroup 2.7K Jun 12 16:00 config.xml -rw-r--r-- 1 jenkins nogroup 5 Jun 26 05:23 nextBuildNumber drwxr-xr-x 8 jenkins nogroup 4.0K Jun 26 05:23 workspace -rw-r--r-- 1 jenkins nogroup 542 Jun 26 06:02 disk-usage.xml drwxr-xr-x 207 jenkins nogroup 12K Jun 26 07:44 builds -rw-r--r-- 1 jenkins nogroup 291 Jun 26 07:45 scm-polling.log
任何想法jenkins有什么问题，我该如何解决？
