A simple userspace application might poll the CQ, find a completion, and then attempt to post a new WQE to the SQ. A spurious error can occur if the userspace application detects a full SQ in the instant before the kernel is able to advance the SQ consumer pointer. This is noticeable when using single-entry SQs with ibv_rc_pingpong if lots of kernel and userspace library debugging is enabled.
