Exchange 2007队列数据库、队列事务日志文件超过临界值(阈值)导致无法接受邮件解决方案
前天,客户Exchange 2007邮件系统突然出问题了。具体表现如下:
只能发邮件,不能收邮件。OUTLOOK中点击“发送和接收”测试,只有正在发送,没有正在接收状态。
查看日志发现如下提示:
The Microsoft Exchange Transport service is rejecting message submissions because the available disk space has dropped below the configured threshold
Resource utilization of the following resources exceed the normal level:
Queue database and disk space ("C:"Program Files"Microsoft"Exchange Server"TransportRoles"data"Queue"mail.que") = 98% [High] [Normal=93% Medium=95% High=97%]
Queue database logging disk space ("C:"Program Files"Microsoft"Exchange Server"TransportRoles"data"Queue"") = 98% [High] [Normal=93% Medium=95% High=97%]
No components were disabled because of back pressure.
The following resources are in the normal state:
Version buckets = 0 [Normal] [Normal=40 Medium=60 High=100]
Private bytes = 0% [Normal] [Normal=71% Medium=73% High=75%]
Physical memory load = 25% [limit is 94% before message dehydration occurs.]
1、确认问题是否由于磁盘空间引起
翻阅资料,发现确实是由于队列及队列日志引起的问题,在微软Technet资料中发现如下说明:“为防止数据丢失,存在 Exchange 可能停止接受邮件的情况。如果 队列数据库的事务日志与数据库位于不同的驱动器上,则这可能是可用磁盘资源不足导致的,此问题表明驱动器太小。”同时,该文中指出解决方案:“通过将队 列数据库移动到较大的驱动器,解决了该问题。”。
