KB15938 - Messages queed while out of coverage are not delivered after outage is over
KB15938 - Email messages that are received while the BlackBerry smartphone is turned off or out of a wireless coverage area are not delivered to the BlackBerry smartphone when it is turned on or returns to a wireless coverage area
Environment
- BlackBerry® Enterprise Server for Novell® GroupWise®
- SDR200708
- SDR163432
- SDR141724
Overview
Email messages that are received while the BlackBerry smartphone is turned off or out of a wireless coverage area are not delivered to the BlackBerry smartphone when it is turned on or returns to a wireless coverage area.
Cause
Email messages that are received in the Novell GroupWise mail server while the BlackBerry smartphone is turned off or out of a wireless coverage area are referenced in the MbMailSync database table. When the BlackBerry smartphone is turned on or returns to a wireless coverage area, this table is queried using a Missed Mail Item poll to retrieve the items to send to the BlackBerry smartphone.
If the MbMailSync table has too many rows, this SQL call can time out. The following error message appears in the Messaging Agent (MAGT) log file:
[MAGT]
[25000] (07/17 00:32:41.595):{0x18FC} RunParameterizedSQLQuery: COM Error 0x80040E31 - IDispatch error #3121 - Source: "Microsoft OLE DB Provider for SQL Server" - Description "Timeout expired" - Command "SELECT MbF.Id, MbF.UserConfigId, MbF.DeliveryStatus FROM ServerConfig SC INNER JOIN UserConfig UC ON SC.Id = UC.ServerConfigId INNER JOIN MbMailSync MbF ON UC.Id = MbF.UserConfigId WHERE ( SC.Id = ? And MbF.Id <= ? And MbF.Id >= ?) And ( ( MbF.DeliveryStatus = ? Or MbF.DeliveryStatus = ? ) AND MbF.Filtered = 0 AND DATEDIFF(Day, MbF.ModifyDate, GetUTCDate()) < ?) ORDER BY MbF.Id"
[30000] (07/17 00:32:41.595):{0x18FC} CheckNewMbSyncRecords() MISSED MAIL ITEM polling returned FAILURE.
If the SQL call consistently times out but the query for new email messages succeeds, then new email messages that arrive in the Novell GroupWise mail server while the BlackBerry smartphone is in a wireless coverage area are delivered, but the email messages that were previously received while the BlackBerry smartphone was out of a wireless overage area are not delivered.
This issue is more likely to occur when there are multiple BlackBerry Enterprise Servers sharing a BlackBerry Configuration Database because the amount of data in the MbMailSync table would typically be greater.
Resolution
This is a previously reported issue that has been escalated internally to our development team. No resolution time frame is currently available.
