We've recently updated to ActiveMQ 5.2.0, and are running it as a
standalone
server, with a config file very similar to the basic example
provided out of
the box. There has been no code change in the Java code that talks
to the
AMQ server. Yet, once started up, the ActiveMQ server process is
restarting
itself every 5 minutes.
Looking at the "activemq.log", I see the following:

So you can see for a while, the broker's adding topics and such, and
then
all of a sudden it gets an "IllegalStateException", and just restarts.
On the clients, when this happens we get this error:

Our "activemq.xml" file is pretty simple - it's almost exactly the

----------------------
And our Java clients use the following URL to connect to the server:
tcp://${jms.server}:${jms.port}?
keepAlive
=
true
&
;connectionTimeout
=
0
&
;wireFormat
.maxInactivityDuration
=0&jms.useAsyncSend=true&jms.prefetchPolicy.all=250"
Notice that I tried setting the connectionTimeout and
maxInactivityDuration
to "0" thinking that this would turn off inactivity checking.
This didn't help. Further, the system does try to send through a
LOT of
traffic when we bring it up, so there's definitely no "inactivity".
As I mentioned, the exact same codebase was working perfectly fine
with
ActiveMQ 4.1.1. There's been no code changes, and no changes in the
nature
of the logs we're sending through. The only change has been
upgrading to
AMQ 5.2.0 on the server side, and using the new jar file on the
Java client side.
Any help would be appreciated, as I'm totally stumped as to why the
server
keeps restarting itself. Our message content hasn't changed,
so why would the EOF file errors or "channel inactive" errors be
happening??
Thanks,
Gary
