SnapCenter 作业无法触发，长时间运行的作业已终止

适用场景

SnapCenter服务器4.1.1x及更高版本

问题描述

• 计划的 默认作业、备份或克隆 作业在20分钟内无法触发。
• 按计划运行的默认作业、备份或克隆可能会提前终止、在WebUI中显然仍在运行。
• 作业启动器、在启动作业时、也会使用SMCore服务通过SnapCenter Web应用程序启动它、这将无法在两个IIS事件之间启动备份(IIS此时不再处理传入请求)。
• SMcore错误消息：
  DEBUG SMCore_28089 PID=[7152] TID=[49] RemoteUrl: https://<SNAPCENTER_SERVER>:8146/JobStatusService.svc/UpdateJobStatus
ERROR SMCore_28089 PID=[7152] TID=[49] WebException in method: Invoke.
   System.Net.WebException: The remote server returned an error: (500) Internal Server Error.
• 系统事件日志将显示ID为5074 (SnapCenter)或5186 (DefaultAppPoool)的信息性IIS事件
  "A worker process with process id of '<PID>' serving application pool 'SnapCenter' has requested
 a recycle because the worker process reached its allowed processing time limit."
• (默认值) 30分钟后、系统事件日志可能会显示ID为5013的警告事件：
  "A process serving application pool 'SnapCenter' exceeded time limits during shut down. The process id was '<PID>'."
• 尽管SMCore已完成操作(备份、克隆等)、SnapCenter也可能会显示以下作业错误：

  We noticed an IIS application pool recycle event when this job was in progress. The final state of this job is unkown.
Consider restarting the job if required.
