[stunnel-users] Poll/Descriptor Problem

I am running Stunnel 4.09 on Mac OS X 10.4 to provide HTTPS service on the standard ports (accept on 443, connect to 80).

All connections are either truncated or dropped entirely, with the following messages written to the log:

------------------------------------------ https connected from ... INTERNAL ERROR:s_poll_wait returned 1, but no descriptor is ready Connection reset: XXXXXX bytes sent to SSL, XXX bytes sent to socket ------------------------------------------

I've tried 4.10, but the result is exactly the same.

Does anybody have any thoughts on what might be going on?

Thanks, John
