Hi all,
I've been busy shifting an existing workload into AWS recently, and a load
test shows a serious performance drop when sending to ActiveMQ which I
could use some advice on.

forwarded as messages to a queue. A backend rec

of more precise wording, go ahead and update but the
performance of the system would appear to be an important factor that

We have a camel route consuming from ActiveMQ (5.10.0 with KahaDB) and
frequently get a DLQ entry without anything logged through our errorHandler.
The only thing we have to go on is a dlqFailureCause header which says:

We have a hub/spoke architecture. We did a rolling upgrade from 5.7.0 to
5.10.0 starting with the hub instance. So long as the client/server & peer

One of our 5.10.0 brokers is reporting memory storage at 70% used. Yet
there is nothing pending on any queues and should be nothing in any topics
either.
The queues and topics look identical to those on another 5.10.0 broker
which sits happily at 0% memory used.
What can I do to debug this?

You should be able to apt-get update then apt-get install activemq and see

We have observed this when the link between A & B is slow. Probably a

Hi,
Just noticed that 5.5.1 has been released (I'm clearly observant!).
However, there's been no news on the front page since April?

Sounds like one for Apache Camel (using ActiveMQ).
Camel to poll a filesystem directory (possibly) to shift the files onto a
queue. At the other end another Camel route to take from the queue and
place into another filesystem directory.

For instance, imagine I want to install a broker that is behind a
customer's firewall, and connect it to a production network of brokers.
HTTP/S might be allowed by the customer for outbound connections but
nothing e
this helps.

This is of interest to me too.
Could use a description of it's behaviour which that page does not provide.

In 5.5.0 with gcInactiveDestinations=true, we've been sending messages via
STOMP with a receipt (proven in the stomp.log).
Just occassionally, the message appears to go missing, as does the queue
itself. The message is set to persist and has an expiry of several days.
Is this an issue that's know

It tells me the output includes a 'size' number. Is that the number of
messages held, the number of topics and queues, or what?

I am looking to monitor (and alert on) ActiveMQ and it's use (queue sizes,

Checking Google first I only see something called AMon as a possibility. Is
there any planned support for SNMP metrics within ActiveMQ natively?
AMon itself looks promising yet is advertised as both free and needing

We have a PHP (STOMP-connected) application that has just read 977 small
packets from one queue (A), processed them, and sent 977 similar messages to
a new queue (B).
Except the broker tells me the queue (B) has 884 messages. There is nothing
dequeuing messages on queue (B).

FWIW I was able to get messages from AMQ to an XMPP user via Camel. I have
not tried using the AMQ XMPP transport directly.

I'm looking for a decent way of managing ActiveMQ, particularly since I'm
now starting to make use of Camel.
This leads me closer to a full Java EE container which might "manage" it
all.
I've seen ServiceMix which seems ok. What others are there and can the
community make any recomendations at al
