We have also seen this issue during marketing promotions on Hybris 6.1.0.2. It seems to happen when a customer is removing an item from the cart (ajax request) and refreshing the cart page during a promotion. It can cause thread contention and is a bad experience for customers. We ran thread dumps using 'jstack -l ' command and observed these thread contention issues.

See attached thread dump.

I'm wondering if this Hybris Bug reported in the SAP Hybris Jira is related: "Cart calculation is not cluster safe when promotion is applied":
