[ofw] Completion with bad status: IBV_WC_RETRY_EXC_ERROR

[Diego Guella]

Hi

I'm trying to port the source example in Mellanox\WinIB\SDK\examples\hello_world to Linux.

The problem I have is this: after I post the WR, I get completion with error:
status = 12 (IBV_WC_RETRY_EXC_ERROR) on Linux;
status = IB_WCS_TIMEOUT_RETRY_ERR on Windows.


What does this error means? I'm not sure about it.
Perhaps am I sending to the wrong LID? to the wrong QPN??

Any help is appreciated.


Thanks,
Diego
