KB01892 - Delayed notifications state for health checks


Environment

  • BlackBerry® Enterprise Server version 2.1 SP3 to 4.1 SP6 for Microsoft® Exchange



Overview

The BlackBerry Enterprise Server debug log displays the following:
[30164] Mail seems to be in 'delayed notifications' state for health checks
where is the number of health checks.
The BlackBerry Enterprise Server receives User Datagram Protocol (UDP) notifications from Microsoft® Exchange when an item in a BlackBerry smartphone user's mailbox is created, modified, or deleted. The BlackBerry Enterprise Server acts on these notifications to determine what has occurred, then takes the appropriate actions. If the BlackBerry Enterprise Server receives one of these notifications and the worker thread responsible for that BlackBerry smartphone user is busy, the BlackBerry Enterprise Server will start a primary counter for that BlackBerry smartphone user. If this primary counter reaches a value greater than 2, a secondary counter is started. This secondary counter is printed in the corresponding debug log entry for this event.
The primary counter has a maximum value of 5. If the BlackBerry Enterprise Server receives a notification and is able to process the event immediately (for example, the worker thread for that BlackBerry smartphone user is not busy), it will decrease the primary counter one increment per notification. If the primary counter drops below a value of 3 for 30 minutes, the secondary counter is reset to 0. Event ID 30164 (in the above debug log entry) is printed only once per BlackBerry smartphone user every 30 minutes if the secondary counter is greater than 0.

OK. So I started seeing this on Exchange 2003 sp2 Server with BES 5.0 just today. Only about 15 users, but it's happening for about 7 of them. They appear to be having calendar problems as well.
