适用场景

Snap Creator Framework (SCF) 4.3.3P8

问题描述

使用数据库插件或运行预处理脚本或后处理脚本时、Snap Cretor 4.3.3P8将无法从第二次使用外部命令或数据库插件调用(通常处于退出静修状态)返回：

########## Application Unquiesce ##########
 [2023-07-11 13:13:22,603] INFO: Application Unquiesce for plugin: db2

(此时日志中的最后一行)

这还会阻止任何新的传入连接、从而导致出现以下错误：

[Wed Jul 19 07:57:23 2023] ERROR: SCF-00059: [Snap Creator Framework 4.3.3P8] dump for plugin [db2] failed with exit code [com.ctc.wstx.exc.WstxIOException: A remote host refused an attempted connect operation. (Connection refused)], Exiting!
 [Wed Jul 19 07:57:23 2023] ERROR: java.io.IOException: Stream Closed

重新启动scAgent只会修复下一个外部/插件调用的问题描述、但会释放该进程(在此、scAgent在将近两天后重新启动)：

[2023-07-11 18:48:44,041] INFO: Application Unquiesce for plugin: db2
