The Processing Manager is filling up the C:\ drive and running out of space.
Change the location of the processing Temp folder. By default, the processing Temp folder is installed at C:\ProgramData\Exterro\Temp if not explicitly changed to another location during installation.
For help configuring the TempDir registry key, see Change ADTemp Location
Note: If your Temp location is configured to another drive, and the Processing Manager is still writing to the C drive Temp folder for some tasks, please open a ticket with Exterro Support so that we can investigate the cause.
