Onlyoffice WebApp heavyRAM usage

Hey to everyone,

It’s the first time I use Onlyoffice via NC in collaboration with someone else (with two persons) and I pretty much like it, but since last time I can not access the “word-file” anymore, because my RAM gets quite stressed from opening the document. This then also causes the page to crash.

Ahm. How can I investigate this further? Happens mostly on Firefox, but have also had problems with Brave. For non-German speakers:
over 10gb RAM goes into the one Firefox tab, in total almost 100% of my memory goes to this task.

See the screenshot.

Greetings
