I have bit of a puzzle.
I have a PC and a rendernode (I produce CGI images and animations). The rendernode is used exclusively for rendering the images, and is a very CPU heavy task.
The problem I'm having is that the rendernode appears to not want to do the "rendering" (when the node should compute the images). Instead it hangs on the stages where it pre-loads the files.
This only happens when I'm not watching the node through a remote desktop app (the node doesn't have a monitor). So to me it appears like the node is in a state of semi sleep, it loads the files, but won't fire up the CPU to render the images. As soon as I connect to the node, it starts to render. I know this isn't coincidence, as no matter how long I leave it, then connect, the rendering is at the same place.
The a similar thing happens once the node has computed the files. It should finish rendering, and save the files to a mapped drive, instead it hangs on this phase too.
Both situations are very unusual, and I have contacted the software guys to see what they say.
Anyway, and suggestions or ideas would be very welcome!
