APC returned failed to write.Check your configuration. error when using fuelphp's apc cache

Good evening.
I run a web service, but I use fuelphp as a framework for the web, and when I was using the fuelphp cache, the following error message appeared.

APC returned failed to write. Check your configuration.

I thought it was an overflow of apc cache, so I tried to load a large amount of apc cache explicitly in the development environment, and when I leaked memory, I got the following error:

Error::shutdown_handler=>Allowed memory size of 134217728 bytes exhausted (tried to allocate 184328 bytes)

Therefore, I thought that the error wording in question is different from the memory leak.
Does anyone know about the error in question?
