Summary0000771: Blocked threads when crawling.
DescriptionI was profiling my Server with YourKit-JavaProfiler eval software.

I was crawling some random sites with my modified code and then reverted back to Github version 1.921/9410.

Both had blocked threads but the Github version had more and my server did a fatal exception dump for reason unknown to me.
I will attach it to a comment.


Additional InformationPossible Potential deadlock: frozen threads found in both versions when monitoring.

Maybe of sum use because of all the code is shifted a little on each file.
hprof5.tar.gz 283 mb site is down

I upgraded to version 1.921/9431 and there seems to be a lot less blocked threads.
See report att.
The Demo Java profiler license runs out very soon (YourKit).
If you need my source I can arrange that I know the line numbers wont match the copy on github.
