[stunnel-users] more than 1000 concurrent connections?

Hi There -

I'd like to use stunnel as the SSL termination point for a bunch of persistent TCP connections.

I'm running it on an EC2 instance and it's only allowing me about 1000 concurrent connections. It doesn't matter if the connections come from one client IP or two.

How can I raise this limit?

I've already raised the OS tcp connection limit with ulimit and it doesn't improve things.

Thanks,

T
