Hi,
thanks to all for adding information.

Hi Rui,
It looks like you're overflowing the Completion Queue. On the application
side, this could manifest as a hang while polling the CQ.
This could happen you receive more completion queue entries than the CQ

Hi list,
I'm seeing the following message:
ib_mthca :0d:00.0: CQ overrun on CQN 380090

Thanks in advance.
