<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I’m assuming you meant fi_eq_sread returns -FI_EAVAIL. The fi_eq_strerror returns the error string for provider (ibverbs/rdmacm) specific error. It is not set
by libfabric. I think it’s probably set by the kernel space code of rdmacm/ibverbs. Did you check the value in err_entry.err ? That could give clues as to what rdmacm error event was received.<o:p></o:p></span></p>
