问题
When I run my test suit, I find that intermittently some of the texts will hang for a very long time (15 mins to half an hour) with PhantomJS constantly reporting:
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW

Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW
Asynchronous Sessions cleanup phase starting NOW ...
What is this Asynchronous Sessions cleanup phase starting NOW and what could be causing it to hang for so long?
Cheers
Dave
回答1:
Solution found:
The Asynchronous Sessions cleanup phase starting NOW ... was caused by some calls to external feeds, these were intermittently slow. This phase must have been waiting for these calls, which were timing out, but PhantomJS sat there waiting for a very, very long time.
Removing these calls when testing (with a wee bit of JavaScript, if host is localhost then use a dummy object) solved the problem.

The workaround that worked for me is to set the takesScreenshot capability to false.
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("takesScreenshot", false);
回答3:
try to use this.driver = new PhantomJSDriver(caps); Now, we get a shutdown. [INFO - 2014-05-01T13:21:09.095Z] ShutdownReqHand - _handle - About to shutdown
But After I got the same pbm
