Because each message includes other data structures, together with a message context that can be significant or small, this behavior affects the behavior of BizTalk Server under heavy stress.
The behavior of BizTalk Server is affected because the engine loads a pre-configured number of messages. These values control the number of messages that BizTalk Server processes or sends at the same time. The HighWaterMark value is the total number of messages that the engine processes at the same time. The default value is messages per CPU. The values that you use depend on the size of the messages.
For BizTalk Server and later versions, you can change the default host throttling settings. If you have identified a memory leak, try to determine the cause by removing custom components or by simplifying a map. Also, try to reproduce the issue by using a simple orchestration or a simple solution. Typically, you should create separate receive hosts for receive adapters.
You should also create separate send hosts for send adapters. When you use this method, each adapter can run in a separate process. Therefore, if your BizTalk Server process experiences an out-of-memory condition, you will know which components are involved. To troubleshoot an out-of-memory condition, use the Debug Diagnostics tool to monitor memory allocations over time. The Debug Diagnostics tool can create and analyze a memory leak dump file. When you troubleshoot memory leaks, the goal is to attach Leaktrack.
For more information about how to download Microsoft support files, see How to obtain Microsoft support files from online services. Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted.
The file is stored on security-enhanced servers that help prevent any unauthorized changes to the file. Use Performance Monitor to collect data about system performance. This data may provide important indicators about the efficiency of your BizTalk Server environment. The goal is to capture process performance over time. Therefore, enable Performance Monitor logging before the memory leak occurs.
Click Start this data collector set now , and then click Finish. Click Add on the Performance Counters tab. Select the following objects, and then click Add after you select each object:. The Sample Interval value and the time to start to monitor are subjective.
These values depend on when the memory leak is reproduced. Because the log file can be large, specify an interval in which you can obtain the information that you must have without overwhelming the server. The New Log Settings dialog box appears. Note the log file location. You can also click the Log Files tab, and then click Configure to change the log file location. In the Performance object list, select the following objects.
Click Add after you select each object. The Data Sampling Interval value and the time to start to monitor are subjective. Click OK. To stop collecting data, right-click the name of the counter log and then click Stop. Creating a Memory and Handle Leak rule with DebugDiag is the recommended approach to capture a memory dump. The Memory and Handle Leak rule automatically attaches Leaktrack. This is used to track memory allocations.
To create the Memory and Handle Leak rule, follow these steps:. Click to select the Start memory tracking immediately when rule is activated check box. Otherwise, you can specify a warm-up time before LeakTrack. Confirm that Autocreate a crash rule is selected. Click to select the Generate a userdump when virtual bytes reach check box, and keep the default value of Click to select the and each additional check box, and keep the default of By selecting the virtual bytes reach option, a memory dump will automatically be created when virtual bytes use MB.
If virtual bytes increases by MB, another memory dump will automatically be created. You can also change the path of the dump file in the Userdump Location box on this page. The rule status is now Tracking. Every time that a memory dump is created, the value will increase in the Userdump Count column on the Rules tab. You can also manually attach Leaktrack. This enables you to control when the memory dump is created. To do this, follow these steps:. Create a crash rule to monitor the same Btsntsvc.
When the process reaches 60 percent to 80 percent of RAM, right-click the Btsntsvc. If the BizTalk process stops before you can create the user dump, the Crash rule should take effect and create the memory dump. If you are capturing a memory dump and Performance Monitor data, stop Performance Monitor logging about two minutes after the memory dump is created.
To help determine the cause of a memory leak, you can use the Debug Diagnostics tool to analyze the dump file. By default, an analysis report file the. The report file will also be displayed in your browser.
The report file contains the results of the analysis. Additionally, the report file may contain recommendations for how to resolve the memory leak. If you use custom DLLs, you can add the symbol path of the custom. If you want help with analyzing the dump file, contact Microsoft Customer Support Services. Posted 10 December - PM.
Is this a work computer? It looks like you definitely need service pack 1a. I can't guarantee that this will fix your leak, but it just might. Either way it looks like you need it. Without this update, you're wide open to infection.
