Hi, Dotan:
When I got that error, I quit my program and use ib_rmda_bw prorgam to
test Infiniband link. It still fails like this:
ib_rdma_bw 10.8.6.3
19068: | port=18515 | ib_port=1 | size=65536 | tx_depth=100 |
iters=1000 | duplex=0 | cma=0 |

19068:main: Completion with error at client:

This means that the remote QP didn't response (or didn't send the
respond in time).
can you try to execute ibv_rc_pingpong between the sides and check what
is the status?
what is the output of ibv_devinfo in both sides?
(maybe something bad happened to the link)
thanks
Dotan
