Hello Sanguine,
I deleted my answer to the other thread you opened for the same issue because this is against SCN engagement rules to post the same question multiple times. So I'll put my response here:
It looks like an exception is ending the processing of the page prematurely: so don't you see any dump, or error message? And did you enhance the corresponding component? (if the answer is yes, then check if this error can be reproduced after your enhancement has been switched off according to note 1311966).
Regards,
Nicolas.
