I contacted official support, where they replied as follows.

It seems that during an item list initialization, there is an infinite loop which causes Workflow Service to crash. It can be due to:

- default value on one of the columns of initialized item list

- initialization itself (either in item list's configuration or by actions like "Update item list values")

Usually, when item list is first time displayed on a form, it's either initialized or default values for its columns are calculated.

I've been looking for the cause for two days now and I can't find a solution. Has anyone encountered anything similar? Any help will be appreciated. Thank you.
