crawler gets hung after downloading a few hits #44

I am trying to use this crawler to build an Urdu corpus. I am running Ubuntu 18.04 inside a VMWare virtual machine. The crawler will start and successfully download a few links but will eventually get permanently hung up. Nothing happens until I ctrl-c to exit the script. I can kill the script, start it again and it will successfully get the link it got hung up on the previous run, it will then successfully crawl a few more until getting hung up again. The below copied text is an example of what I get when I kill the script with ctrl-c

...(the crawler has successfully downloaded several links so far)...

Hi, thanks for the report. I just tried running corpuscrawler on urdu, and it has gotten quite a bit farther along than you have reported. I hate to say that it may be a problem with your internet / ISP blocking the requests to bbc.com.

For now I'm going to close the issue. If you can test using different wifi networks or running the tool on a different machine (such as a GCP instance), and if you still can reproduce the issue, please re-open the ticket. Thanks!

After seeing your reply I dug deeper and found that I was having a massive ping spike on my wireless connection exactly every 10 seconds. I think this has been causing me problems with other software as well. I searched online and found a fix, and now Corpus Crawler works perfectly and is running right now! Sorry I blamed my hardware problem on your program!
