Fatal error: Out of memory (allocated 1916534784) (tried to allocate 44 bytes)

This error is reported when the program runs. memory_limit = 1024 M in php. ini
I don't know what's going on.
------ Solution --------------------
Memory_limit is used to limit the maximum memory available for php.
You memory_limit = 1024 M
But 1827.75 MB is available!
It should be said that your php version is faulty.
