If you are running PhantomJs, did you encounter any issues like memory leaks and socket errors ?

I'd be interested in the solutions you used to solve issues like that if it's not proprietary / private.

Also interested, I've tried similar things with watir webdriver and a xvfb/headless mode but the only real 'solutions' I've come across are time-outs. Needless to say it could've been heaps better.

I didn't do much testing since PhantomJS 2.0 but I know that in the past, it was recommended to reload PhantomJS every +/- 50 pages to free the leaked memory.

We're running HTMLUnit [1]
