We have even tried running Stunnel separately on a Linux distro (FC4), with even less positive results.
That's strange. I was testing stunnel with over 10k connections on Linux 2.6.18. You just need to make sure ulimit values (e.g. file descriptors) are high enough. http://stunnel.mirt.net/perf.html
_beginthread: Exec format error (8) Connection rejected: create_client failed
Fascinating. What is the resource utilization (memory, threads, etc.)? It looks like there's a limit of 1000 threads on your Windows 2003 server.
