Hi Gary,
We also have observed this problem, when the backlog piles up (e.g. for some
reason consumers are disconnected, like network outage) producers as well
slows down, even when producer flow control is disabled, send is
asynchronous.
Thanks and regards

Thanks for the tip. I didn't have JMX on when it slowed down. I've turned
it on now and am waiting to see if it happened again.
Question - am I right in understanding that flow control will turn on
automtically when the rate goes over a certain level? Will it then shut
off?
Second question. I

I've poked around a bit and haven't found anything in the forum or docs.
I created what is supposed to be an asynchronous consumer. I found some code

This worked once or twice, but I cannot get it to work a
Hey Gary,
I will try to write a testcase but based on my Jprofile it looks to me
contention is for write lock due to removeMessages() calls after they
receive the ack from the client side and the incoming producer messages.
I am going to play with producer-flow-control settings and other

I want to email WARNINGs and above in my log file to myself, but I'm having
trouble getting the Log4j SMTPAppender to work in ActiveMQ. I created a
small java test program and verified that my Log4j SMTPAppender properties
are correct and that I can send myself an email, but when I copy these

I also noticed this problem. When there is high throughput and consumers
get bogged down working in between messages, they eventually get dropped
and must re-open a connection or they will stop receiving messages.
The problem with that is that consumers will have to actively monitor
their connect
on the results of your jprobe profiling, it would be good to identify
if there is a real contention problem there.
If you can generate a simple junit test case that demonstrates the
behavior you are seeing, please open a jira issue and we can
investigate some more.
A test case will help focus the a

Any suggestions/hints? Let me know what additional details I can provide.

Thanks for your reply Jason!
That link you provided recommends the use of PooledConnectionFactory if I am
publishing messages - which is OK for B2 endpoint in my above example and
recommends using MessageListenerContainer for consuming messages which is
for B1 endpoint. This also correlates to an

You can't really enforce the maximum number producers you actually have
