GreasyPenguin14 how long as we talking about? 🙂

theoretically the entire document cannot exceed 16MB, but I'm sure that's not the realistic limit you're talking about

With a name of 98 characters errors like 'munmap_chunk(): invalid pointer',
'double free or corruption (!prev)' or 'free(): invalid next size (normal) occur later in my script. But maybe this is not related to clearml but to the filesystem. Just wondering if there was a maximum length from the clearml side

Shouldn't be related to ClearML. If you can copy/paste the error I'll be happy to take a look 🙂
