Can't crawl all pages

After 3000-7000 successful crawls, the program gives an error.
It just says "An error has occured (link)" and goes back to the start screen.

is there any way to fix this in the config or does an option exist to download first 0-2000, then 2050-4000 etc. to avoid this error? Shouldn't be a ram problem as I have 64 GB DDR5

Thank you!
