Getting Error: Cloud not read open message due to buffer having less bytes than open message size

[Hekkel]

Hello, I'm trying to connect BMP with a CoreEMU instance.
Everything looks fine until I start getting events, then I get this error

As you can see in the logs I configured the buffers using persistant config with 300Mb (tried with 8,16,32....all the way up to 300mb) but I'm still getting that error message, which by the way has a typo: Cloud -> Could.

Any ideas/suggestions what I'm doing wrong?
Thanks in advance.
