[stunnel-users] unexpected shutdown of stunnel

[Daniel Graupner]

Hello,

I use Freebsd and made an update from stunnel 4.8 to stunnel 4.10 from
the ports today. Now I noticed that stunnel stops after a while.

Here is my conf:
chroot = /usr/local/stunnel
pid = /stunnel.pid
setuid = stunnel
setgid = stunnel
debug = 7
output = /usr/local/stunnel/stunnel.log
client = yes

[https]
accept  = localhost:9999
connect = <ssl-apache>:443
TIMEOUTclose = 0

And these are the last lines of the log:005.05.15 10:34:00
LOG7[60990:0]: Waiting 0 second(s) for 3 file descriptor(s)

Everything went fine with 4.8, now stunnel is not running anymore after
a short period of time (few minutes).
