數據驅動的訂閱超時連接

我有一個數據驅動的訂閱，它每次運行顯示報告管理器中的「待定」狀態。然後在一點點後出現錯誤數據驅動的訂閱超時連接

Error: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated.

我在這裏沒有做任何特別的事。我的檢索用戶的sproc只返回2條記錄（並立即在Management Studio中執行）。報告的數據也不是什麼奇特的。它從3個數據源中提取大約3條記錄 - 基於通過參數傳入的ID的所有非常直接的選擇。

當我設置此報告以定期訂閱發送時，它工作正常。只有在數據驅動時它纔會超時。

我的配置中的超時設置爲默認值（120秒）。

以下是日誌所說的內容。

我試着用本地管理員帳戶（誰也是sa）製作一個新的數據源，我仍然得到超時。這份報告沒什麼特別的。它實際上只是帶有少量數據的格式化文本。我正在使用SSRS來處理髮送格式化的電子郵件。我唯一擔心的是運行SSRS的機器只有2.0 GB RAM。這可能會導致超時？但是爲什麼當我爲一個用戶執行報告時，沒問題，但是對於2個用戶來說，這個用戶是kablooey？
