Can you please tell me what a sleep interuppted error is?
I started the crawler, but realized that I forgot to put an exclude for *.css extentions. So, I stopped it without saving and reloaded my former saved project file that I had saved prior to running the crawler. The former saved project file only had settings saved to it. BUT, when I started the crawler again, 2 of the 5 threads I was running stayed at 0 B/s for several minutes. So, in the crawler tab, I selected the corresponding threads and stopped then re-started them. When I did, I got these sleep interuppted errors.
What does this mean?
Can I re-crawl these urls?
How?

OK, I closed the browser and re-started from scratch and it seems to be working. I will post if I run into more problems.
