during development of a tridion TBB, i stumbled upon a weird error. I uploaded a new version of my TBB dll, and tried to preview one of my pages to check the result, and i got this error

XmlResponder failed render request :

After some investigation, it turns out there is nothing wrong with my code, but the problem comes from windows. In the callstack we can see there is a call to the function 

System.IO.Path.InternalGetTempFileName(Boolean)

This function takes care of creating a unique temp file in the c:\windows\temp directory. After inspection of this directory on my CM (development) server, I noted that this folder contained about 240000 temp files. After moving these temp files (i didn't want to delete them), the error no longer appeared.

So, i should set a rule to periodically clean up this temp folder. I'm wondering why tridion wouldn't clean up these files

  • That is indeed unusual - I don't have that on my servers. Maybe they're left behind because the process crashed somehow and didn't clean it as expected? Maybe as result of debugging efforts?

  • 240K temp files? Yikes, that's a lot. Since you found the answer to your own question, can you accept it (by clicking the check mark to its left)?

  • Hi Harald - with regards the temp files - do these appear to have been created recently, in a batch/time frame?

  • Same issue with us, we could not upload new files, finish workflows, or even preview. Our fix was not only the Temp drive for upload but the AppData > Local > Temp for the "MTS User" needed to be cleaned up as well. C:\Users\[MTSUser]\AppData\Local\Temp

After doing some google search, I came to know that

The Temp directory having more than 65,353 folders, will start causing this issue.

As @Harald said, it requires periodical clean up.
