Indeed, it was one of my first bug reports :)

Incredibly, this machine is still running woody (is the last one), so
the problem is still present and I had set a cronjob for restarting
the daemon each day. So I'll disable the cronjob and try this, I'll
report in a few days. But I wonder if this has any relevance nowadays,
since I'm still using the woody version of the package!

Thanks!!
