Hi!

When I try to run ibv_srq_pingpong as non-root-user, I get the error
"Couldn't create QP[5]".

The tail of strace is:

) = 22
exit_group(1)                           = ?

As root-user everything is working fine...

Does somebody have an idea, what's going wrong?
I assume, I did not set the rights accordingly for some files?

Thank you!
