at javax.servlet.http.HttpServlet.service(HttpServlet.java:584)
at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:799)问题原因：前端响应超时
解决办法：
需要修改以下4个文件。
/api-server/ui/assets/service.33119ae9.js
/api-server/ui/assets/service.33119ae9.js.gz
/ui/assets/service.33119ae9.js
/ui/assets/service.33119ae9.js.gz并找到以下配置，然后将 15e3 修改为 15e5 或更高版本。
baseURL:"/dolphinscheduler",timeout:15e31.这里 service.33119ae9.并不是固定的名称，只要找到 service..js*的文件修改就行
2.如果使用docker部署的dolphinscheduler。是没有/ui/assets/service.33119ae9.js和/ui/assets/service.33119ae9.js.gz文件，忽略就行
3..gz文件使用vim就可以打开
4.重启api服务
5.清除浏览器缓存

解决办法：更改bin/dolphinscheduler-daemon.sh的api-server项内存大小参数
Docker部署解决办法：
1.进入Docker实例
docker exec -it bbd60fe717af /bin/bash2.修改/opt/dolphinscheduler/bin/start.sh
vim /opt/dolphinscheduler/bin/start.sh3.内存参数从‘-Xms1g -Xmx1g -Xmn512m’ 修改为‘-Xms2g -Xmx2g -Xmn1g’。具体数值根据需要资源修改

org.apache.dolphinscheduler.api.ApiApplicationServer3.12 BUG
修复任务组可能被多个任务抢走的问题 #13115
如果设置任务组，多个任务会抢占任务组不释放，导致master一直重试释放，无法继续执行任务
解决办法：
1.升级到3.13
2.取消任务组
