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.
> Wire format negotiation timeout: peer did not send his wire format

> Key: AMQ-3290
> URL: https://issues.apache.org/jira/browse/AMQ-3290
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.3.2
> Environment: MS Windows 7 Home Premium x64 Intel Core i5 M 460 RAM 6GB
> Reporter: Maxim Novikov
> Priority: Critical
> Labels: connection, did, failed, format, negotiation, not, peer,
> send, timeout, wire
> Attachments: hs_err_pid24632.log

> Original Estimate: 24h
> Remaining Estimate: 24h

> 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 628
> at Apache.NMS.ActiveMQ.Connection.CheckConnected() in
> c:\dev\NMS.ActiveMQ\src\main\csharp\Connection.cs:line 712
> 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 454
> 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 occasionally.
> 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.
