Steps to reproduce

Hi,

I am having an issue where my CardDAV contacts don't always sync if there is a photo present on the contact. I believe I've narrowed it down to contacts with a large photo, but the actual size that fails I haven't been able to narrow down.

I had found this ticket, which seemed promising #897 but it appears to not apply to me since I'm on Linux, not Windows.

I have looked at the Apache / PHP logs, but found nothing that indicates a problem. I've also enabled logging in Apple Contacts, but no problems appear to be present there either.

To reproduce, this is what I do:

1. Add an Apple account for Baikal using an SSL connection.
2. In the macOS Contacts application, copy an existing contact with a fairly high resolution photo from another account to the Baikal account.
3. Wait a few minutes and see if the numbers change in the Baikal dashboard, to no success.

If I do the above steps on a contact without a contact photo it syncs fine. If I try to copy multiple contact cards at the same time without a photo, it works fine. Sometimes, hit or miss, when I copy a contact with a small photo it works fine. It never works with a modern high-resolution contact card photo.

At first I thought maybe there was a file size limitation in my PHP configuration. I boosted it from 2M to 20M which should be more than enough. I also changed the buffering settings per the Baikal documentation to no success. The temporary directories are readable and without size constraints.

Does anyone have any ideas here? Are there specific logs I should be looking at or looking for?
