周四接到客户电话,说邮件出了问题,晚上重新启动了一下,就好了,也没有在意。可是周五下午突然又坏了,同样症状,找不到原因,很抓狂。
过了24小时之后,看到了错误信息,开始有点谱,仔细研究,终于搞定了。
In Exchange Server 2007, the Transport service monitors system resources such as disk space and memory on Transport servers (the Hub Transport and the Edge Transport servers), and stops message submission if it is running low on these resources(4G free space). It continues to deliver existing messages in the queue. When resource utilization returns to normal, it resumes message submission. The feature is called Back Pressure.
Many configuration options for transport servers are saved in an XML file named EdgeTransport.exe.config (it’s the same file name on both server roles— the Edge Transport and the Hub Transport servers) located in Exchange ServerBin. You can edit the file to:
Disable Back Pressure or
Modify the parameters to more accurately define what’s high utilization for your deployment or server configurations.
