Nope, nothing fancy. Backend/frontend both reside on the same host and
use a local partition for storage.

Are those IOBOUND messages anything to worry about? It would seem to me
that autoexpire will almost always being doing it's deleting while the
backend is trying to write, since that's when the free-space limit is
exceeded.

Makes sense. I'll throw the sleep() in there for now, until you have a
chance to implement your other plan. 

If there's anything you would like me to try to test why sendEvent()
isn't waiting, let me know. I'm running RH7.3 w/qt-3.1.1, if that
matters. Everything else has been working great for a number of months
now.


Thanks for taking the time to look into this.
