[ofa-general] ibv_modify_qp() return value 22

[Joerg Zinke]

Hi,

ibv_modify_qp() fails with return value 22 when I try to open a new CM
connection under load (already ~3000 RDMA connections opened). I tried
to figure out what return value 22 means but could not find it in the
mthca kernel driver.

Any hints? What does return value 22 mean?
I use OFED-1.1 under debian with vanilla kernel 2.6.18.

Regards,

Joerg
