KB04789 - Restarting the BlackBerry Enterprise Server services may cause delays in message delivery


Environment

  • Devices with BlackBerry® Built-In™ software
  • Devices with BlackBerry® Connect™ software
  • BlackBerry devices
  • BlackBerry® Enterprise Server
  • Microsoft® Exchange
  • SDR67514



Overview

When you restart certain BlackBerry Enterprise Server services, you may experience a delay in email message delivery to the BlackBerry devices. The BlackBerry Enterprise Server services that may cause messaging delay include the following:
For BlackBerry Enterprise Server software version 3.6
BlackBerry Server
where is the name of the BlackBerry Enterprise Server instance.
For BlackBerry Enterprise Server software version 4.0 through 4.1
  • BlackBerry Controller
  • BlackBerry Dispatcher
The length of the delay can vary depending on conditions within specific environments. Some of these conditions can include (but are not limited to) the following:
  • Mailboxes on the messaging and collaboration server that contain data in excess of 1GB. The BlackBerry Enterprise Server completes a full mailbox scan when the BlackBerry Enterprise Server services are started. Email messages are not sent to individual BlackBerry device users until this scan has been completed. The scan determines if there are any items in each BlackBerry device user's mailbox that need to be processed by the BlackBerry Enterprise Server. The larger the BlackBerry device user's mailbox, the longer the scan process takes.
  • A large number of BlackBerry device users exist on the BlackBerry Enterprise Server (for example, 300 or more). When the BlackBerry Enterprise Server services are restarted, a full mailbox scan is completed for each BlackBerry device user. These scans are run parallel to each other. The length of time it takes for the initial resource load to subside varies. The initial resource load may cause messaging delays for the BlackBerry device users. In order to minimize the impact of potential messaging delays, the BlackBerry Enterprise Server services should be restarted during non-production hours unless it is necessary.
  • Slow network speed. During a mailbox scan, the BlackBerry Enterprise Server accesses the Microsoft Exchange Server where the BlackBerry device users are located. If requests sent from the BlackBerry Enterprise Server or the responses from the Microsoft Exchange Server are delayed, the time to complete the mailbox scan will also be affected.
  • Messaging server performance. The BlackBerry Enterprise Server waits for responses from requests made to the Microsoft Exchange Server. If the Microsoft Exchange Server is slow to respond to the BlackBerry Enterprise Server requests, messaging delays may occur.
  • The BlackBerry Enterprise Server services have been stopped for a long period of time. The longer the BlackBerry Enterprise Server services are stopped, the more pending email messages there are in the BlackBerry device user’s mailbox. The BlackBerry Enterprise Server has more to process when the BlackBerry Enterprise Server services start up again.
Note: Repeatedly restarting the BlackBerry Enterprise Server services is not recommended. This will cause the mailbox scan to start each time the BlackBerry Enterprise Server services are started.
