[ofa-general] Question: Verbs API Error code recover

[Wei Fang]

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?
