[ofa-general] ***SPAM*** Error returned by ibv_poll_cq()

[Karthik Gopalakrishnan]

Hello.

ibv_poll_cq() returns IBV_WC_REM_ACCESS_ERR or IBV_WC_WR_FLUSH_ERR in
wc.status and IBV_WC_SEND in wc.opcode. The async event handler
simultaneously reports IBV_EVENT_QP_ACCESS_ERR. I could not find a
description of these errors either in the man pages or in verbs.h. I
would be grateful if someone can tell me under what circumstances
ibv_poll_cq() would return those errors.

I am using the following adapter.
