我在OpenStack Icehouse中使用Cloudify 2.7。
我为Glassfish开发了一个服务配方，它将实例注册到Apache Load Balancer。
start事件执行glassfish_start.groovy文件，该文件运行以下命令：
su - glassfish -c "asadmin --passwordfile /home/glassfish/passwd.gf --user $userAdmin start-domain $domain"
su - glassfish -c "asadmin --passwordfile /home/glassfish/passwd.gf --user $userAdmin deploy --contextroot \"/\" $warName"
在开始活动结束后，我可以看到：

为什么要调用停止检测？
此外，the Cloudify docs说明了这一点：
已知限制：如果您的启动脚本返回，Cloudify会将您的服务实例视为已停止，因此会尝试再次配置它。要避免此行为，请确保您的启动脚本永远处于休眠状态。
我该怎么办？
