The movie features Sandra Bullock, Cate Blanchett, Rihanna and Anne Hathaway.
The producers of the movie have a counselor on call to make sure the women get along, reported OK! magazine.
"There have been a few arguments, and certain people haven't gotten on as well as they'd hoped," a source said.
"They want to make sure the cast and crew have someone to vent any frustrations to, so nothing gets taken out on another actor. The aim is to wrap the movie on a good note and set the stage for later promotion," the source added.
Directed by Gary Ross, "Ocean's Eight" is set to hit the US theaters on June 8 next year.
