Free Gift Promotion - Cart recalculation issue

[Former Member]

Hi, we are using hybris 1811.8 and the OOTB free gift promotion and when reloading the cart we get this model saving exception:

Sometimes we then have no products in the cnd when refreshing again the products are back

i checked one possible solution from https://answers.sap.com/questions/12753211/view.html but it did not work for us.

Any suggestions what might cause this problem?

Hi Jacoob,

the issue is mostly due to concurrent or parallel requests on cart one for viewing the cnd one of them for recalculation. pls find the parallel ones and make them one after other to resolve the issue.
