[Answer]-Dajaxice randomly stops working

Actually dajax and dajaxice are anymore improved so it is unwise to use them:

Should I use django-dajax or django-dajaxice?

In a word, No. I created these projects 4 years ago as a cool tool in
order to solve one specific problems I had at that time.

These days using these projects is a bad idea. (…) If you want to
use this project, you are probably wrong. You should stop couplig your
interface with your backend or… in the long term it will explode in
your face.
