Subject Are messages lost if a stomp producer is quick
Date Mon, 14 May 2007 04:49:18 GMT

Hi Guys,

    I just downloaded ActiveMQ SNAPSHOT v.4.2.0 last night and tried a
simple test with Stomp Python ( That is, I ran a producer sending
100 of 1K messages consecutively (without any pause) to a queue. Things went
OK when I ran the test on a PowerPC1.4GHz Mac OS X notebook. Running the
same code, however, on an SMP (4 Intel Xeon 3GHz CPU) Redhad Enterprise 4, I
saw only 93 messages successfully sent to the queue. I then coded the
producer to pause (0.01ms) a bit before sending each message to the queue
and things went OK. I also tried ActiveMQ v.4.1.1 and I got the same result.

    Therefore, I would like to know, if someone could please answer:
        - Is my stomp producer supposed to pause always?
        - Is ActiveMQ supposed to be able to handle this situation?
