DLP Endpoint temp files

Hello,

At a customer they have the DLP Endpoint instaled with the Default configuration.

The DLP endpoint is creating a lot of temp files as the user folder (...userName/AppData/Local/temp)

The files are numbered:

DLP0000.tmp

DLP0001.tmp

...

DLPFFFF.tmp

8440 files, all with 1kb!

And the users are complaning of slow machines.

What are thoses files?

The policy have a a File Retention responce rule.

If we manually delete the temp files the machine gets back to good performance. But not much time later the temp files are back and the performance is damage again.

Help!!!
