Is there any way to override the FD_MAX setting (64 IIRC), perhaps as a stunnel.conf option?

stunnel.conf with more than 64 sections is pretty impressive...

MAX_FD was increased from 64 to 256 in stunnel 4.16.

I could also rewrite stunnel to remove the limit completely (to dynamically allocate the file descriptor list).

Best regards,
