Abdelkader,
How do you configure stunnel? Do you use
--with-threads=fork
option? Why?
Otherwise please send us your config.log.
There is indeed a regression issue with FORK threading model.
I'll fix it in the next release.

It seems that the 'num_clients' variable is undeclared in the

Hello Michal,
Indeed, I'm using
/configure --build="x86_64-unknown-linux-gnu" \
--prefix=${STUNNEL_DIR} \
--mandir="${STUNNEL_DIR}/man" \
--docdir="${STUNNEL_DIR}/doc" \
--enable-ipv6 \
--disable-libwrap \
--disable-fips \
--with-threads=fork \
--with-ssl=${OPENSSL_DIR} \
--enable-shared \
--disable-static
As far as concerns the threading model, several linux distributions use
the fork model. Also
http://devblog.bu.mp/post/40786230183/introducing-stud
seems to conclude the same way. Actually, I'am not really sure about the
best threading model under RH Linux. Maybe, can you give some advices.
