Production message "stream error WebSocket frame length too large"

I have a fine running production app but when lately checking the logs I read lots of entries of the following:

[]: stream error WebSocket frame length too large

but I can’t find any stack trace, nor is it causing any crashing or undesired behavior, ultimately I could not find this message in the codebase of the Meteor framework repo.

Anybody experienced this before?

So I found out when this message occurs. I wrote a function that transfers the fs.chunks via remote DDP connection to my app.

It seems that the amount of data is simply too large for the DDP protocol? Is there someone with some deeper experience in DDP and the ejson?
