After upgrading to stunnel 5.19 I noticed the log file no long reports the pid of stunnel processes. Instead I find the constant string [0].

Sep 14 12:15:30 hostname stunnel: LOG6[0]: SSL closed (SSL_read)

This information is very useful to isolate individual connections. Do later stunnel versions report the pid correctly? 

I am using fork mode. My syslog is defined as local6.debug and stunnel.conf contains debug=local6.info. 

Thank you.
