Hi, I'm looking for some help with a problem I'm having with librdmacm.
I have been using the select() call to detect when a disconnect event is pending on the rdma_cm event channel (while also waiting for completion queue events). On the client side, things seem to work fine. On the server side, I get a false positive from select() if I'm also waiting for completion notification on a completion channel. If I comment out any one piece of the code involving the completion event - the ibv_req_notify_cq(), the ibv_post_send(), or the FD_SET(comp_channel) - then I do not get the false positive. But if I've done all the steps necessary to detect the completion of my send operation, select() returns immediately with an indication that the rdma_cm channel is readable, though a call to rdma_get_cm_event() just blocks because there are no events pending. Any insights into what the problem might be? I can provide code for a simple client and server that demonstrate the problem. I've been testing on a system with SLES 10, and the librdmacm version appears to be 1.0.11.
