During OpenMPI scale up testing, we observe rdma_connect failures if ports are reused on multiple connections. This is because the Control Queue-Pair (CQP) command to add the reused port to Accelerated Port Bit VectorTable (APBVT) fails as there already exists an entry. Check for duplicate port before invoking the CQP command to add APBVT entry and delete the entry only if the port is not in use.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
