Has anyone ever seen this sync failure from Marketo to SFDC?

The weird thing is that my records are still making it over into SFDC, but I'm seeing the above sync failure in my records activity logs in Marketo.

This can sometimes happen when you have sharing/visibility rules enabled in SFDC and the lead which Marketo created is invisible to the sync user because of the rules.  I would check there first.
