重新启动Openshift MySQL墨盒时出错

Question

我有一个带有 Tomcat 7 和 MySQL 5.5
的不可扩展的OpenShift应用程序，并且该应用程序仅在其上运行了一个小型Java应用程序。该应用程序运行了好几个月，但是从上周开始它停止工作。当我尝试使用OpenShift仪表板重新启动应用程序时，出现以下错误消息：

Starting MySQL 5.5 cartridge

显然，MySQL卡式盒无法以某种方式重新启动，但是我没有更改Java应用程序或齿轮配置中的任何内容。

有人知道为什么会这样吗？我不想简单地删除MySQL并再次添加它，因为如果我不确定根本原因，将来可能会再次发生此问题。

提前致谢。

我建议检查您的配额，以查看您是否已达到限额。尝试摆弄齿轮并运行以下命令quota -s。如果已达到配额，则可以rhc tidy在本地计算机上使用命令来清理齿轮。
