SYMPTOMS

You frequently experience performance issues when you use BizTalk Server 2006. For example, you receive Single Sign-On (SSO) time-out error messages. Additionally, the BizTalk Server 2006 Administration console stops responding. If you use the following SQL statement to determine the size of the <BizTalkHostName>Q_Suspended table, you find that the table contains many rows:
Select count (*) from <BizTalkHostName>Q_Suspended
Note <BizTalkHostName> is a placeholder for a customer host name.

Additionally, some throttling messages for the database size are logged in the performance log file.

CAUSE

This issue occurs because zombie messages are created for the cache service instance. The bts_UpdateMsgbox_BizTalkHostName stored procedure calls the Insert statement to move these zombie messages into the suspended queue. Then, the slow execution time of the stored procedure blocks many other BizTalk Server-related SQL scripts.

Based on the BizTalk Server 2006 mechanism, the large suspended messages for the cache service instances in the database create a throttling problem. This problem occurs when the peak workload value is larger than the default throttling value for the database size.

Note By design, users cannot retrieve or terminate these suspended messages in the BizTalk MMC.
