Just upgraded stunnel and getting the following error message in the
/var/log/messages file. It appears that when I restart stunnel it complains "Error binding pop3s to 0.0.0.0:995 and bind: Address already in use (48)". therefore the 995 port never becomes available during the restart. Why is that happening? She the stunel logs below.


any clues?
