Text between stderr.txt & no validation

Hi, I've noticed that all the 3 workunits that I've run on my new computer so far (just see http://einsteinathome.org/task/7839658 for an example) are showing "error messages" between the tags "stderr_txt". And, what's more, none of them has been sent to other hosts since then.
The result page just shows a message like this:

What do those skipped runs mean? Is there a problem with my PC or is it normal and I just have to wait until they're sent out to other hosts? :)
