It keeps telling me that the server is “too busy” or “taking too long time to respond”; in addition, it seems that if I press “Enhance” and switch to another tab before it completes the job, it interrupts it.

=================

After I got Sasha's message, I tried running VIEW in multiple tabs simultaneously, and I ran into similar problems.

The VIEW server is taking too long to respond.
Occurs when the ajaxtimeout is reached, this is currently set to 60 seconds.
So if a ajaxrequest takes longer than that, we get this message and the VIEW server will abort the enhancement.

The server is too busy right now. Please try again in a few minutes.
Occurs when a CAS can't be checked out (cas = null) in which case it will not process the page until a CAS can be checked out again.

According to my testing, the second message occurs after the first message was observed earlier. So one error is causing the other.

I tried out to reproduce the problem and I get different results. In my case I can switch between tabs and it will still enhance the page. Also, when I switch tabs, I can't even press the enhance button, because its not visible (same as the abort button)

Note that not every page is processed equaly fast. Pages with a lot of ads and nested markup will take a long time to process (sometimes hitting the ajaxtimeout) which causes this chain of errors.
For instance I got a timeout for this page:
http://www.pravda.ru/news/accidents/08-05-2015/1259326-vasilyeva-0/
but this page is processing very fast, never reaching the timeout (I always take this page for testing):
http://www.bbc.co.uk/russian/international/2014/08/140814_russia_convoy_whereabouts.shtml

Other than increasing the timeout limit I can't thing of another solution for this.
