All good, I thought I’d ask. I did a quick test to confirm some basics…
In the basic test I did it over wrote the out_000000.jpg file already in the output directory.
I’m sure a little scripting hackery would sort it out, however I ended up doing the blunt tool approach and start all over again. So far the server has remained up.
I tried setting the nice value to see if it would make any difference, not sure that’s really working as it is used I think to solve CPU utilisation contention not so much ‘slow’ a program down by having less time on the CPU.
