If I remember it correctly (loooong time since I wrote that code), the queue info file by default is only written when necessary, which I think means on shutdown only. This is done in order to save performance. HOWEVER, there is a setting that permits you to specify how often (I think in number of messages enqueued) the .qi should be written. If you set that to a sufficiently large value, the performance impact should be minimal. I think the queue doc has this parameter: http://www.rsyslog.com/doc/queues.html Search for "checkpoint" on that page.
