[stunnel-users] Output to neither stdout nor stderr it seems

Mon Nov 10 15:51:05 CET 2014

Hi stunnel-users

I run stunnel4 in docker with the following config file:
--- /etc/stunnel/stunnel.conf --------------
sslVersion = SSLv3

pid = /var/lib/stunnel4/stunnel4.pid

socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

verify = 2
CApath = /etc/ssl/certs

debug = notice
output = /var/log/stunnel.log

client = yes
foreground = yes

[foo]
accept  = 1234
connect = 127.0.0.1:2345
TIMEOUTclose = 3
---------------------------------------------------------

When I run stunnel and pipe stdout and stderr to /dev/null, I still get output:

root at 849b7eb3bbd0:/# /usr/bin/stunnel4 /etc/stunnel/stunnel.conf
2>/dev/null >/dev/null

Complete shell output is attached.

Any hints on what's happening?

Kindly,
