Warning: Error while sending QUERY packet. and QLSTATE[HY000]: General error: 2006 MySQL server has gone away:

Whereas my setup can easily display the field values using the normal image formatter, and also in a regular view, it crashes when using formatter_view. My configuration has no problems displaying nodes with 10 images but there is one node with 97 images in one field and it won't render with field_formatter_view.

The view actually renders fine (but very slow) if I remove the image field and just load a view of image:delta text fields. I think this proves it's a resource constraint issue. I know this can be fixed by tweaking settings like MySQL max packet size etc. but I still wanted to report here because I think it's strange I've never ran into this issue before and I'd prefer to optimize the module where possible before settling for increased server resources.

Full Warning and Error with call stack:
