This feature includes code to allow a system with compressed ARC enabled to send data in its compressed form straight out of the ARC, and receive data in its compressed form directly into the ARC.

This commit is causing a panic on the receiver of a compressed stream.

I can provide the dump

Hi Gernot, the dump would be very helpful! Can you either post it in a place I can access it, or send it to me at ? Thanks very much!

#4 Updated by Gernot Strasser over 1 year ago

As it looks like Dan has left Delphix can anybody else look into this?
The problem remains and this feature is dangerous for the receiving side.
I have a dump available, but I guess this can be easily reproduced.
