Same behavior occurs after upgrade.

on debug 7:

This part of the logs:
2006.01.04 09:00:39 LOG7[9605:0]: Waiting 43200 second(s) for 5 file
descriptor(s)
2006.01.04 09:00:39 LOG7[9605:0]: CONTEXT 1, FD=4, (IN)->()
2006.01.04 09:00:39 LOG7[9605:0]: CONTEXT 1, FD=6, (IN)->()

2006.01.04 09:00:39 LOG7[9605:0]: CONTEXT 2, FD=9, (OUT)->(OUT)

loops continuously in both server and client lots the entire time,
repeating several times each second. One rsync session over stunnel
generates stunnel logs over 50MB. I have no idea if this is typical
LOG7 behavior or not, but I'm mentioning it just in case.
