Apc caching and warning message

I have build in apc-caching in cakephp 3 but sometimes I get this warning messsage:

warning (2):apcu_store(): GC cache entry ‘cake_dbsdjlfksjdsdfsdf_expires’ was on gc-list for 3680 seconds

I think I have missed something in my setup but I 'don’t know how to solve this problem.
Did somebody had a similar message and got a solution?

pretty much Appreciate for any help
