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

Hi, All:
I'm new here just some days ago. Right now I'm facing a problem to
using OFED 1.2.5's verb api. In my programming, I use RDMA Write
function to transfer data ( ibv_post_send ). Then I use ibv_poll_cq
to get this CQ's finish. Sometimes, ibv_poll_cq's return error is
IBV_WC_RETRY_EXC_ERR (error code is 12). When this error code
happen, any next transfer will always fail. In this case, I have to
restart computer. Anyone can tell me how to recover this error
without quit program or restart PC?
If you have a completion with status IBV_WC_RETRY_EXC_ERR your QP
state will be moved to error, so all of the WR that you will post
after this will fail too.
If you have this failure you need to reconnect the QPs (i don't know
why you need to restart the computer in order to fix this ....).
I think that you need to check why you got this completion status from
the first place (did the remote side close the QP?)
