Troubleshooting
Problem
The following error is seen by using the "export to DOORS" feature in Microsoft Word. CRCRD7208Q: DOORS memory usage is at XXXX Mb. You might continue to execute the code until the next warning level of 1000 Mb but DOORS might crash losing any unsaved data.
Cause
This warning is issued because of the memory consumption of the DOORS client. By default, this message is displayed when the DOORS client consumes more than 1000 MB.
This error message was especially useful when the DOORS client was 32bit and therefore could not allocate more than 2000 MB of memory by default. A bit more if Microsoft Windows was configured to be Large Address Aware, in which case, the limit was 3000 MB on a 32bit windows, and 4000 MB on a 64bit windows.
Since the DOORS clients are now 64bit applications, the amount of memory allocated is not limited anymore. But the warning message remains by default (which can still be useful).

Resolving The Problem
Currently, the warning message is the expected behavior in DOORS. The registry entries can be used to determine when the message appears.
This can be achieved by adding the MEM_LEVEL_WARN string value in the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Telelogic\DOORS\9.6\Config
Set the value of MEM_LEVEL_WARN to:
You can also define another string value in the registry (at the same location): MEM_LEVEL_CLOSE
This value defines the threshold over which DOORS starts closing modules automatically in order to save memory. The default value is 1000 MB.
The variables are also mentioned in the following link:

You can get rid of this warning message completely, or increase the memory consumption threshold over the value that is mentioned in the warning.
This can be achieved by adding the MEM_LEVEL_WARN string value in the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Telelogic\DOORS\9.6\Config
Set the value of MEM_LEVEL_WARN to:
- Either 0 to prevent the warning from being displayed or
- For instance, 4000 to increase the threshold (values are expressed in MB).
You can also define another string value in the registry (at the same location): MEM_LEVEL_CLOSE
This value defines the threshold over which DOORS starts closing modules automatically in order to save memory. The default value is 1000 MB.
