WARNING as java.io.EOFException when ActiveMQ starts
提问by divinedragon
am trying to start the ActiveMQ 5.11 and I see a WARNINGas below:
我正在尝试启动 ActiveMQ 5.11，我看到WARNING如下：
WARN | Transport Connection to: tcp://127.0.0.1:40890 failed: java.io.EOFException
My activemq.xmlis as below:
我activemq.xml的如下：

Can somebody tell me why are these exceptions thrown?

So, I finally got to the root cause of this. This WARNINGcomes because the way networkConnectorworks and configured. I had posted this on the activemq community here - http://activemq.2283324.n4.nabble.com/java-io-EOFException-when-ActiveMQ-starts-td4717598.html
所以，我终于找到了这个问题的根本原因。这WARNING是因为方法networkConnector有效和配置。我已经在 activemq 社区上发布了这个 - http://activemq.2283324.n4.nabble.com/java-io-EOFException-when-ActiveMQ-starts-td4717598.html
When networkConnectoris used, activemq tries to connect to the broker configured. In my case, I was trying to self-connect to the broker and that is why it was rejecting the connection. The same was pointed by Timin the community.
当networkConnector使用时，ActiveMQ的尝试连接到配置的代理。就我而言，我试图自我连接到代理，这就是它拒绝连接的原因。社区中的蒂姆也指出了这一点。
I've never tried configuring a broker with a static networkConnector connected to itself (why would I, it's a useless configuration), but it wouldn't surprise me if the broker rejected that self-connection, which could result in the EOFException you saw. It's also possible that there's something wrong with your SSL configuration as you suggested; there's no good way in a mailing list discussion to check whether your truststore trusts your keystore and the certs are being presented properly since that's all about the binary content and you shouldn't be sharing that publicly, but you could test the SSL configuration by setting up two brokers (in a test environment) that each have their JMS_X_SITE_CSV_URL pointed at each other. If that configuration gives you EOFExceptions, then switch to using the tcp transport and see what happens. If you get errors with the ssl transport but not the tcp one, there's a good chance it's something wrong with your keys.
As far as the current configuration (where you have a broker whose only networkConnection is a static:ssl: one to itself), it's not a useful configuration (having a networkConnector to yourself serves no purpose), and you proved early on in this discussion that removing it removes the WARN log line that you're concerned about. So I disagree with your statement that "I feel the configuration still seems fine." Either switch to something that serves the purpose you said you're trying to achieve (like the discovery: transport instead of the static: transport, or like listing your cross-site servers if you're going to continue using the static: transport) or take it out and eliminate the WARN line.
我从来没有试过用一个静态的 networkConnector 连接到自身来配置代理（为什么我会，这是一个无用的配置），但是如果代理拒绝那个自连接，我不会感到惊讶，这可能会导致你看到的 EOFException . 正如您所建议的那样，您的 SSL 配置也可能有问题；在邮件列表讨论中没有好的方法来检查您的信任库是否信任您的密钥库并且证书是否正确显示，因为这都是关于二进制内容的，您不应该公开共享这些内容，但是您可以通过设置来测试 SSL 配置建立两个代理（在测试环境中），每个代理的 JMS_X_SITE_CSV_URL 相互指向。如果该配置为您提供 EOFExceptions，然后切换到使用 tcp 传输，看看会发生什么。如果您遇到 ssl 传输错误而不是 tcp 传输错误，则很有可能是您的密钥有问题。
就当前配置而言（您有一个代理，其唯一的 networkConnection 是一个 static:ssl: one toself），这不是一个有用的配置（拥有一个 networkConnector 给自己没有用处），并且您在本次讨论的早期就证明了这一点删除它会删除您关心的 WARN 日志行。所以我不同意你说“我觉得配置看起来还不错”的说法。要么切换到符合您所说的目的的东西（例如发现：传输而不是静态：传输，或者如果您要继续使用静态：传输，则列出您的跨站点服务器）或将其取出并消除 WARN 行。
So, networkConnectoris essentially of no use if it is a single broker system. Makes more sense in multi-broker deployments and then all the brokers are configured, except the self on each broker separately.
因此，networkConnector如果它是单个代理系统，则本质上是没有用的。在多代理部署中更有意义，然后配置所有代理，除了每个代理上的 self 单独。
To still make the networkConnectorconfiguration to work in single broker deployment, the value I had to set was - url="static://(ssl://divinedragonbox:7031)..."(Hostname instead of IP Address or localhost). That gets rid of the WARNINGwhich comes.
为了仍然使networkConnector配置在单代理部署中工作，我必须设置的值是 - url="static://(ssl://divinedragonbox:7031)..."（主机名而不是 IP 地址或localhost）。这摆脱了WARNING来的。
回答by Matt Pavlovich
Those EOFExceptions indicate a client connects to the broker, then disconnects without cleanly closing the connection. Typical culprits include tcp/ip monitoring agents and incorrectly coded clients.
这些 EOFExceptions 表示客户端连接到代理，然后在没有完全关闭连接的情况下断开连接。典型的罪魁祸首包括 tcp/ip 监控代理和错误编码的客户端。
