SQL Server Long Running Transaction - WAITFOR(RECEIVE conversation....DatabaseMail)

Question

I have recently implemented an Agent Job which checks SQL Server every 10mins for any long running queries and if detected it will send out a mail to recipients with the information. However since putting this in, I notice alot of the below query and wonder if this is something I should be concerned about:

WAITFOR(RECEIVE conversation_handle, service_contract_name, message_type_name, message_body FROM ExternalMailQueue INTO @msgs), TIMEOUT @rec_timeout

从数据库邮件中了解它，等待信息是 (1x: 62093ms)BROKER_RECEIVE_WAITFOR 但我是否需要担心或只是将其从警报中排除。

通过 sp_whoisactive 查看可以看到 open_transaction 计数为 1，状态为挂起。

任何帮助表示赞赏。

根据我的经验，你应该忽略它。此查询来自使用 SQL Broker 的程序。这是正常的。该程序只是等待 SQL Broker 以这种方式通知它。（当然，等待 SQL Broker 通知会产生长时间的等待。）

我们正在使用 Broker，我也有同样的事情。
