Windows Server 2008 R2 SP1; Citrix Xenapp 6
Files with names in the form SETnnnn.tmp are accumulating every day on Citrix farm servers in the C:\Windows\System32 directory. The nnnn is a 4-digit hex number in the name of each file. (such as SETB14A.tmp or SET1A02.tmp)
Each file has the same date (2/25/2009 7:01 PM) and size (497 KB). The files are owned by SYSTEM. Opened a couple of them with Wordpad and I can make out the filename of DIFxAPI.
These farm servers have been online about 6 months, with SP1 installed about 2 months ago. The first time I found them each server had about 15,000 of these .tmp files. At night, with users sessions logged off, I deleted these. Next day, a couple of hundred more were created.
Since these files are only accumulating on these servers and no others with Windows 2008 R2 SP1, it’s pretty clear that it’s related to sessions. In searching on this, I’ve seen others mention these files but no specific reason as to why they are created or why they aren’t being deleted automatically. But this would seem to indicate that it’s related somehow to Terminal Services rather than Citrix software.
Does anyone have any information as to why these tmp files are created in the System32 folder and why they aren’t being deleted automatically when the process finishes?
TIA
