Tzachi,
Thanks for your quick response. Our system is Linux, how do I
do it?
Also when ibv_create_qp() fails, is there a way to figure out
what the reason is (QP limit reached, unable to lock memory, others)? Does
errno tell us anything?

Subject: RE: How many QPs are used so far?
Hi,
The number of allowed qps is controlled in the registry.
Before we try to debug your system, I would like to try and change that number
and see if this will solve your problem.
Can you go to the registry to the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mlx4_bus\Parameters and
increase the key that is called LogNumQp?
Please stop and start the mlx4_bus from the device manager and repeat your
experiment.
Thanks
Tzachi

Subject: [ofw] How many QPs are used so far?
HI,
Our application sometimes report ibv_create_qp() error. Our
system has 69G memory and set lockable memory to unlimited. So I wonder running
out of QP number is more suspicious than running out of memory.
Is there a way to query how many QPs are used at the point of
ibv_create_qp() failure ?
Thank you in advance.
