Jan Wedel commented on AMQ-4660:
--------------------------------
Hmm, the question is: Why does it happen with 60 messages? In issue AMQ-4595,
the had 10000 messages. Right now, after some messages have been consumed,
there are 28 left, and these messages are displayed instantly.
However, I've checked the body size and each message contains about 20kB of XML
(don't ask my why, its not my code). But does browsing actually needs to
acquire the body for displaying a list of message ids?
And even if its been done, this would be 60*20b=1,4MB which should be fine when
running AMQ with 1GB of heap, shouldn't it?
Also, they were talking about the auditDeph, which is set to > 2000 by default.
So this appears not to be the same issue at least from my outsider's point of
view.
Unfortunately, this is a live-system. I will try to deploy the dev version on
one of our development servers.

> I ran AMQ with {{-Xms1024m -Xmx1024m}} settings an there is no system-based
> memory shortage, afaik. So I'm wondering why its not possible to 60 messages?
> Once I purge the queue, I am able to view it again.
