Hello,

Probably this is an obvious newbie question, but I got to the following
problem:

I am using stomp (opening and closing the connection every 1000 messages
sent), configured persistent messages, and a durable consumer listening on 1
topic.  I am trying to have a fairly constant throughput.
Messages are about 1k in size, and I start detecting the errors after about
18000 messages are sent. 

Are these errors known issues, or could it be due to a faulty configuration? 
I am worried some messages might get lost, although for the moment the
broker seems to keep them safe.

Cheers,
daniel
