Symptoms: 
You are using the External Machine Translation (EMT) for ITD-based tasks. For some larger tasks, the EmtApplyExecutor archiver plugin may time out when retrieving data from the Machine Translation provider. 

When the plugin retries the retrieval action, it does not find the already created temporary .sdlxliff file and therefore throws the task in Recovery with a message indicating "Converter callback message: Warning: Unexpected error when detecting file type".

Explanation: 
When the mechanism used to retrieve data from the machine translation provider was trying to retrieve data for the second time after a first time out, it was looking for that .sdlxliff temporary file.

Unfortunately, this file would have already been deleted at plugin timeout. Without that file, the retry action could not proceed and SDL TMS would be sending the file to Recovery.

Resolution: 
With this fix, the temporary file is now preserved in the folder and the task proceeds properly through the EMT retrieval step.

SDL-hosted customers should contact SDL Support to arrange for this hotfix to be deployed.

Customers who host SDL TMS themselves should download the installer forSDLTMS11.0.1 Hotfix for TMS-9396.exe from the following FTP site: ftp://sdlpatches:5dlpatch35@ftp-emea.sdlproducts.com/SDL TMS/11.0/CU1/Hotfix.

Note: 
This issue was detected in SDL TMS 11.0.1.
