Hi
I try to use activemq but I always get some issues:
I produce a load of 360 messages/sec on the "OIconveyer" Queue
and read with a camel component from this queue
first it works fine:
write (360 messages/sec)
read (400 messages/sec)
but after a while its getting lesser and lesser till its zero
and ActiveMQ throws the following error:

**********************************
I have a really powerful box 32 cpu 16 MB Ram - Sun
and the cpu load is at 7 percent
my activemq configuration is:
(I added " persistent="true" " to broker tag because I heared that this
should help something)
The problem I have that it should never happen that the jms stops taking
messages - it should store them persistent
Please need help!!!
