Fonts Stop Embedding Halfway through a Composition in FusionPro 10 API

[ReminderVDP]

I've managed to recreate this issue a second time in FusionPro 10 API. I will send a data file to the hot folder that has maybe 1,100 records total in the file. It will start composing. The files are fine and then around record 500 or 600, the fonts stop embedding in the output PDF.

The files keep writing until they are all composed and there is nothing in the msg file about a font error or embedding issue. We output our files in batches of 100 records so 200 pages per file, each page is different.

Has anyone else experienced this with version 10? I'm using 10.0.16 right now. The first time this happened was in version 10.0.3. Same exact issue.
