由于GC促销失败，应用程序线程停止运行。
我已经阅读了一些建议添加CMSInitiatingOccupancyFraction和UseCMSInitiatingOccupancyOnly参数的文章。
但这些已经添加，任何帮助将不胜感激。
我使用以下参数：
-Xmx4g
-XX:NewSize=3g
-XX:MaxNewSize=3g
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:+CMSParallelRemarkEnabled
-XX:+CMSClassUnloadingEnabled
-XX:CMSInitiatingOccupancyFraction=80
-XX:+UseCMSInitiatingOccupancyOnly
