The Queue size for the BizTalk Host - BizTalkServerApplication
The threshold for the “BizTalk:Message Box:Host Counters\Host Queue - Length” counter has been exceeded.
This monitor watches the value of the “BizTalk:Message Box:Host Counters\Host Queue - Length”” counter for a given system. If the value exceeds the preset threshold, which is set to 100 by default, then the state will change from healthy to critical. This monitoring is configured by default to generate an alert when the state is changed to critical.
Potential causes include the following:
The server is unable to keep pace with the incoming load
The server may not be processing according to expected capacity
The purge jobs in the message box may not be completing successfully
The SQL Agent service may not running
Verify that the systems are keeping up with load, healthy, that purge jobs are enabled and running without errors and that the SQL Agent service is running on all message boxes.
