Analysis of TCP Connection Failures Caused by ARP Queue Length (unres_qlen) in Linux Kernels

The article investigates intermittent TCP connection failures during application server startup caused by the Linux kernel ARP queue length parameter unres_qlen, reproduces the issue with a concurrent connection test, analyzes kernel internals, and recommends increasing unres_qlen for kernels prior to 3.3.
