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.

Fascinating.  What is the resource utilization (memory, threads, etc.)?
It looks like there's a limit of 1000 threads on your Windows 2003 
server.
