I'm playing with Sun's OpenMQ. The Java-based installer made me fairly skeptical (c'mon guys... tar zxf...) but boy howdy! so far, utterly rock solid. After my pitched, losing battles with SpiritWave in the 2001-2003 timeframe, I'm fairly skittish and approaching this project at Gilt with caution.
So far though...
(Yes, I tried ActiveMQ as that would be my first choice due to the utterly irrational reason of tribal affiliation, but I've managed to lock the ActiveMQ broker up fairly easily with a simple stress test, and waiting to hear back on the user list regarding what I did wrong. So while I'm waiting, I'll play with OpenMQ and try not to fall in love.)
