Thanks for reporting this!

I now had the time to look into this issue and I'm a bit confused how this can fail, as we allocate the memory directly above, so I don't see any reason the pointer should be invalid or even null.

However, the error is only printed and the thread continues processing the data send. The worst thing that should happen is a minimal performance degradation.

I don't see how this situation can be improved in any way, would you be ok with closing this for now?

Yep sure, thanks for looking into it.
Just something we noticed while running Pixelflut with > 100Gbit/s continuous (real world performance) at GPN22.

Maybe it should be noted in the README that this is known?

Sure, raised a PR for that, happy about review! #29
