Transport failed: java.io.EOFException
I notice this error (logged as debug) from time to time in the AMQ logs:
java.io.EOFException
at java.io.DataInputStream.readInt(Unknown Source)
at org.apache.activemq.openwire.OpenWireFormat.unmarshal(OpenWireFormat.java:267)
at org.apache.activemq.transport.tcp.TcpTransport.readCommand(TcpTransport.java:156)
at org.apache.activemq.transport.tcp.TcpTransport.run(TcpTransport.java:136)
at java.lang.Thread.run(Unknown Source)
I'm using AMQ 4.1.2. Maybe this is expected behavior? Or has it been fixed in later versions?
Thank you

Ok, thanks.
It reproduces consistently when I start Geronimo with amq logging set to debug. It happens on al Geronimo deployments I was using (my local workstation and two company managed deployments). I think I also saw it once when a subscription was created. I will past more logs tomorrow.
Doesn't look like it effects functionality, but I can't be 100% sure
Upgrading to 5.x seems to be the way to go. Thanks again

It's difficult to say why this exception is being thrown without a lot
more detail. Not only the exception a generic one, but it also
provides no guidance about the actual cause. Are you able to
consistently reproduce this exception or does it happen randomly?
FWIW, ActiveMQ 4.1.2 is about three years old now and no more fixes
for the 4.x version will be released. If possible you might want to
consider upgrading to the latest release which is currently 5.3.1.
