[stunnel-users] FreeBSD upgrading to 4.41 (Dispatching signals from the signal pipe)

Thu Aug 4 19:51:35 CEST 2011

Hi, I just upgrade stunner on a  FreeBSD server from 4.35 to 4.41 using the ports, I restarted the server and notice that stunnel was not listen to any port, I had to manually restart it so it could work again.

I increased the debug to 7 and got this when booting:

This is my conf:

cert = /usr/local/etc/stunnel/smtp.inbox.pem
chroot = /usr/local/var/stunnel
setuid = stunnel
setgid = stunnel
pid = /stunnel.pid
debug = 7
output = /stunnel.log
client = no
foreground = no

; Some performance tuning
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

[ssmtp]
accept  = 465
connect = 25

[ssmtp2]
accept  = 587
connect = 25

Any ideas of what could it be wrong? the last 2 lines of the boot log tell me that the ports i specify are been closed but why? 

2011.08.04 17:45:42 LOG7[688:675287360]: Dispatching signals from the signal pipe
2011.08.04 17:45:42 LOG7[688:675287360]: Service ssmtp closed FD=11
2011.08.04 17:45:42 LOG7[688:675287360]: Service ssmtp2 closed FD=12

thanks in advance.
