Hi I use this to compile stunnel: The gcc and openssl is from Solaris SFW. # export CC=/usr/sfw/bin/gcc # ./configure --with-threads=pthread --with-ssl=/usr/sfw --localstatedir=/var After installing and starting stunnel, I found there are mutiple stunnel processes. There is a PID file which store one of the stunnel process. I have tried to kill that PID, stunnel is bring down. But there other stunnel processes running. Any ideas? Regards Patrick
