Error Message => 'Currently Window handle/name is invalid (closed?)

[luksch]

Hi, I have a running a java program that uses the phantomjs webdriver. All runs fine and stable, but if I start about 8 or nine processes that all use phantomjs but access different sites I get the above mentioned error. not always in the same program, and not easily reproducable. I just notices the correlation with many instances of phantomjs, but that is all. Can anyone tell me what is going on here? I use a 16Gig/Ram 8 processor 64bit ubuntu box for running all this and the machine is not really at a limit with the 8-10 processes.

Regards, Lukas

here is the full error log, in case that helps:
