[syslog-ng] HUP to syslog-ng does not close files

I'm upgrading from syslog-ng 2.0rc3 to 2.0.7. One thing that no longer works is when I send syslog-ng a hangup signal the currently open files aren't closed and reopened when the config file is reread. I verified this by running an lsof on syslog-ng and I see that it has files open that say "Deleted" next to the filename in the lsof output. If I send syslog-ng a hangup signal without deleting I files I do see a log entry that the config file is being reread. Because of all this I have had to change the restart line in the logrotate configuration from "syslog reload" to "syslog restart". Is this expected? Thanks, Beirne
