Hello,
I have a problem with one of our customers concerning the Workflow service. I noticed that the service wasn't started, so I restarted it manually. After a few seconds, the service stopped again. I couldn't restart it; it just kept stopping.

I can't get hold of the customer's IT department (which is a service provider) to find out if they've done a maj or something.

In the event viewer, this is what I get:

The C: disk is in the red, but there's still 48G free. On the other hand, one of my workflows needs to copy files to a remote server, which is full. Could this be where the problem lies?

Thanks in advance.
