Is this old bug still there? See if this helps.

I modified stunnel to use the builtin daemon(3) function rather than
its own code to drop to the background. This fixed the problem for
me. However, I am not really sure why. The source for the daemonize()
function in stunnel and the daemon(3) source are pretty much identical.
Anyway, I dropped this patch into,
/usr/ports/security/stunnel/patches/patch-az
Before I did a make and it worked fine,
