Cannot initialize API Client

@sun_4220  - they probably upgraded to a new version that supports more memory. Rather than tagging onto an old thread, maybe you should start a new one with whatever problem you'e having.

freeing memory is not possible by script and even not by FDK

Glad to here diabling autospell check works (at least that way the books process well).

There are some other memory issues in FrameMaker which cause these memory effect. Maybe SVG graphics could be another cause.

Check if Memory behavior is the same when you process both books by hand, So you can be sure (or not) that it's not your script which causes these problems.

With FM2019 some of These effects are solved. And with FM 201964bit FM is able to allocate more RAM so this will also solve this out-of-Memory issue

Edit > Preferences > Spellchecking > Options

Checkbox: Auto spell check

1100 MB is the value where FM runs out of Memory...

Closing Files is an approach indeed, if it solves this issue, you'll see.

Please deactive auto Spellchecker, to be sure you don't run into same trap than me.

Otherwise it's hard to find a good algorithm to avoid Memory issues. Good luck with this.

Otherwise try FM2019 64bit, that's the easier way

this Error-Screenshot just means: FM has crashed no more Information available

This is an error at FrameMaker startup I think. Are you starting FrameMaker fresh for each book?

you run the same process für 2 (different) books. The first ist OK the seconds has this error. So why are you assuming that Content is OK, when content is different?
