Fetch failed : java.lang.NullPointerException

Hi All

While crawling my seed list, I bumped into this Null Pointer Exception for
few urls. What could be the problem.

Please find paste.bin link of my hadoop.log file

Thanks

HI, Roannel,

I have the following enabled:
protocol-selenium|protocol-interactiveselenium|protocol-http|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|indexer-solr|scoring-opic|urlnormalizer-(pass|regex|basic)

I now think it is because of my network environment. It hasn't happened
ever since.

Thank you.

Hi, I have the same problem. The following is part of my log: 
http://pastebin.com/JjkJ1qe6 

It seems there is a read time out. But I paste the url in the browser and it works fine. 

Any ideas what could be causing this problem? 

Thanks.

I don't see any null pointer exceptions coming up in your log. Do you have
any more info or perhaps I'm missing something?
