问题描述

在对PostgreSQL执行SnapCenter自定义插件(例如)时、备份失败并显示以下错误：

SCC-00164: Application quiesce for the plug-in [PostgreSQL] failed with exit code [102] and with error :Operation failed. Reason: The watchdog killed the running operation. Verify that plugins/wrapper/wrapper binary has execute permission set. Increase the WRAPPER_TIMEOUT_IN_MSEC value in agent.properties if operations require more time to complete.

从作业日志中可以看到以下内容：
