Apache，PHP，"I/O警告:加载外部实体失败“有时

Question

我正在尝试在VPS安装CDash。通常，在重新启动apache之后，它可以正常工作一段时间，但是几分钟后，它会随机地开始失败，并出现以下错误：

Warning: XSLTProcessor::importStylesheet(): I/O warning : failed to load external entity "/cdash/footer.xsl" in /cdash/cdash/common.php on line 55
Warning: XSLTProcessor::importStylesheet(): compilation error: file /cdash/ line 4 element include in /cdash/cdash/common.php on line 55

Warning: XSLTProcessor::transformToXml(): No stylesheet associated to this object in /cdash/cdash/common.php on line 65

我正在使用UbuntuServer13.10。我尝试了CDash 2.0.2和SVN主干的最新版本，结果都是一样的。

我通过在libxml_disable_entity_loader(false);文件开头添加cdash/common.php来解决这个问题。受https://stackoverflow.com/questions/20534866/intermittent-simplexml-load-file-i-o-warning-on-local-joomla-site启发
