我们有一个大型项目（约35,000个java文件），目前有大约10,000个问题。大约3个星期前，我们的夜间扫描开始失败版本sonarqube 6.5。我升级到6.6并发现了同样的问题。首先，它由于堆空间而失败。我升级了这台机器，为它提供了更多的内存，这似乎让分析完成了。现在，在后台任务期间，扫描每晚都会失败，因为“＃太多”打开文件＆＃34;。我们已经为声纳用户提高了打开文件的限制，但这似乎没有任何效果。我们有其他较小的项目，他们都很容易完成。只是这个非常大的项目经常失败。谁看过这个吗？
今天早上我安装了sonarqube 6.7以确定是否修复了它。我目前正在进行分析，但完成并失败大约需要3个小时。
我们增加了声纳用户允许的打开文件数。
