Subject [jira] [Commented] (AMQ-3290) Wire format negotiation timeout: peer did not send his wire format
Date Wed, 29 Jun 2011 18:52:28 GMT


Timothy Bish commented on AMQ-3290:

You should attempt to create a test case to demonstrate the issue.  Problems like this usually
appear when the number of connections to the broker exceeds the number of open file descriptors
that the OS allows.  It would be helpful to see what your code is doing.

> I have two client application written on Java. Each of them has consumers to ActiveMQ
(maven dependancy 'activemq-core' version 5.3.2).
> Also there are three applications written on C# (two windows services and one ASP.NET
application) which use Apache.NMS 1.5 to connect to ActiveMQ server.
> During some time everything's fine (e.g. today this period has been about 4 hours). But
since some moment .NET started throw the following exception:
> Wire format negotiation timeout: peer did not send his wire format.
> Apache.NMS.ActiveMQ.IOException: Wire format negotiation timeout: peer did not send his
wire format.
>    at Apache.NMS.ActiveMQ.Connection.SyncRequest(Command command) in c:\dev\NMS.ActiveMQ\src\main\csharp\Connection.cs:line
>    at Apache.NMS.ActiveMQ.Connection.CheckConnected() in c:\dev\NMS.ActiveMQ\src\main\csharp\Connection.cs:line
>    at Apache.NMS.ActiveMQ.Connection.CreateAtiveMQSession(AcknowledgementMode ackMode)
in c:\dev\NMS.ActiveMQ\src\main\csharp\Connection.cs:line 467
>    at Apache.NMS.ActiveMQ.Connection.CreateSession() in c:\dev\NMS.ActiveMQ\src\main\csharp\Connection.cs:line
> Actually Java consumers also don't work though there are no errors in their part. But
I can see via ActiveMQ web console that no one Query has consumers (for each Query column
'Number Of Consumers' value equals 0).
> So actually nothing works (not Java, not C#) since some moment. I can see the error in
.NET but can't see in Java.
> Also this problem appears after restarting operation system. Not always but it happens
> PS For Java application I use org.apache.activemq.ActiveMQConnectionFactory and Mule
ESB jms:activemq-connector. And this part doesn't show error when it happens.
> For C# applications I use Apache.NMS.ActiveMQ.ConnectionFactory and every time when I
think we can face to problem I'm trying to get new connection with the following code lines:
> if ((connection == null) || !connection.IsStarted)
> {
> 	connection = factory.CreateConnection();
> 	ISession session = connection.CreateSession();
> 	IDestination dest = session.GetDestination(Queue);
> 	producer = session.CreateProducer(dest);
> }
> but unfortunately it doesn't help.
