I have customers running Cygwin-based Kannel on both Windows Server 2003 and Windows Server 2008 R2, but it’s nowhere near that amount of messages (it’s in MDM deployments, where sending SMS is just a support function), and while there are some random crashes it works quite nicely all in all for those setups.

Of course – it’s great that there are people testing the more demanding scenarios as well I would assume that setting up a dedicated Kannel box on something *nix-based would scale better for a load like that.

It’s probably worth mentioning that Cygwin is unfortunately not stable enough under load to allow Kannel under Cygwin to be production stable.

I’ve done quite a bit of work with Kannel running under Cygwin on Windows (both W7 and Server 2003) in recent weeks. When subjecting Kannel to 30,000 messages Cygwin will just crash. Both the Bearer Box and the SMS Box services have to be restarted.

The Kannel user-group have confirmed that Cygwin’s p-threads are the issue.

But as a test environment Kannel under Cygwin is great.

Hopefully this fix would apply to your installation as well:
You need to edit a file – gateway-1.4.1\gwlib\thread.c
Comment out the following lines:

if (mutex->owner == gwthread_self())
panic(0, “%s:%ld: %s: Managed to lock the mutex twice! (Called from %s:%ld:%s.)”, \
__FILE__, (long) __LINE__, __func__, file, (long) line, func);

And you’ll have to re-compile too. I’ve only seen this on Windows XP, not on Windows Server so it might be something related to the OS as well.
