You are working in Trados Studio and suddenly the application crashes and you receive the following error message: Exception of type 'System.OutOfMemoryException' was thrown.

Depending on the file type used, the error must also be There is an error in XML document (x, y).

There are some preventive steps that you can take in order to avoid this error from occurring:

• use any system management tool to clear some disk space and temporary folders so that Windows can build enough disk cache if required;
• if you have large files to translate (such as complex Word files or PPTX files) make sure that you are not using other applications that consume a lot of RAM memory (a good example is Google Chrome or any other browser);
• monitor your RAM usage by opening the Task Manager (CTRL+SHIFT+ESC) > Processes and constantly checking what applications consume most RAM memory and make sure that you close them if they are not required at that moment.
• restart Trados Studio and try again

If you know that you constantly work with complex or large files the best option would be to add more RAM memory to your computer and install a 64-bit operating system to make sure that all RAM memory is being used.

Note: See this article for more details on physical Memory Limits for Windows and Windows Server Releases: https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx

If you are using a computer that has a maximum of 4 GB RAM, it is very probable that you have exceeded the RAM physical capacity which causes the application to stop.

When working on large files (SDLXLIFF larger than 100 MB), the error may also occur when you have the necessary RAM capacity.
