It's now been two days since the pauses were last observed, so I think the problem is solved. The last thing I did was to substitute a gigabit switch for the 10/100 switch I had been using. I'm guessing something about the Optiplex 755's NIC didn't play well with MySQL on a 10/100 switch. With the gigabit switch, there have been no more pauses, and everything runs smoothly.

I have a Rivendell machine (Debian 6/RD version 2.5.5) running rdairplay on a network where it is using /var/snd and a MySQL database residing on a second machine (also running rdairplay).

What I am observing is that rdairplay on the first machine (but not the second, where /var/snd and the database reside) will occasionally pause for several seconds while the audio continues to play. At the end of the cut, however, there will be a pause before the next cut starts.

I've never seen this behavior before; if there were droputs in playback, I'd suspect a network problem, but in this case ecah cut will play in its entirety, even though rdairplay may pause in the middle of the cut, and there will be a delay of some seconds before the next cut starts.

I'm guessing this is a MySQL issue. Are there parameters I should try tuning in my.cnf? If so, on which machine? The machine exhibiting the pauses is not the one hosting the database.

Thanks all.
