My comment was just based on what I can see in "z3.log" after running
"zopectl logreopen" :

This output is just the same as what I can read when starting Zope.
Also, as you can see, I'm using a ZEO client storage and Twisted web
server ; I only found "logreopen" and "SIGUSR2" references in ZDaemon
source code, and I thought that default server for Zope-3.3.1 was
Twisted...

Thanks (as always) for any complement...
