Dcc.Store Memory limit


I have a question. I use the dcc.Store in memory type. So I would sugggest I do not have memory limits like in in seesion or local mode. But i get the error message:

Traceback (most recent call last):

  File "/usr/lib/python3.5/gzip.py", line 262, in write
OverflowError: Size does not fit in an unsigned int

So I think its a qzip problem with files larger than 4gb? But I read that qzip nowdays accepts files get larger than 4gb?

I hope someone can help me.

Best regards!
