[libfabric-users] "Local Protection Error" with verbs provider

[Jörn Schumacher]

Hi,

fixed it! It turns out in my code the memory regions were not always 
allocated large enough.

For others:
"Local Protection Error" is issued when memory is accessed by the verbs 
provider outside registered memory region. This error indicates an issue 
with registering MRs.


Cheers,
  Jörn
