I just saw that this problem in logfiles. The warning says:

Warning: igbinary_unserialize(): Function Symfony\Component\Cache\Marshaller\DefaultMarshaller::handleUnserializeCallback() hasn't defined the class it was called for in vendor/symfony/cache/Marshaller/DefaultMarshaller.php on line 80

The relevant part of the backtrace looks like this:

Fixed in igbinary 3.2.3 in

Looking at - If you're using Symfony's DefaultMarshaller, it looks like it will throw because a class that existed in whatever serialized that data did not exist and could not be autoloaded when you unserialized the data.

- i.e. this warning may just be a symptom of a different issue in your application

The exceptions from user-defined callbacks will continue to be thrown in igbinary 3.2.3, but igbinary will no longer emit the notice (based on php's unserialize(), it is only intended to be emitted when configured callback for unserialize_callback_func didn't exist)

I meant "it is only intended to be emitted when configured callback for unserialize_callback_func was called, failed to define the class, *and didn't throw*"
