Hi,  
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

Michael
