[stunnel-users] Log to syslog without process name, after reloading the configuration (sighup)

[Reschke, Sven (VWIF G-TS/P)]

Hi,

I've upgraded my stunnel from version 5.44 to 5.45.
After reloading the configuration of stunnel (via pkill -sighup stunnel) several times, I've stumbled about missing syslogs.
Only the loading of the configuration file was still visible.

Then I've noticed, that greping the syslog for stunnel was my mistake.
Stunnel doesn't log its process name after reloading the configuration file the second time (see logs below)

Can someone verify, or is it just me, or some configuration I'm missing?
BTW: I've reproduced the "problem" also for the version 5.48 as you can see from the logs. With version 5.44 stunnel always logged its process name to syslog.

Syslog output for greping after "stunnel":
