Have you checked the Tomcat source code and the JVM source ? That may give you more help.

I think your general thinking is good. I would expect a <code>ConnectException</code> in the scenario that you couldn't connect. The above looks very like it's client-driven.

I have seen this most often when a corporate firewall on a workstation/laptop gets in the way, it kills the connection.

eg. I have a server process and a client process on the same machine. The server is listening on all interfaces (0.0.0.0) and the client attempts a connection to the public/home interface (note not the loopback interface 127.0.0.1).

If the machine is has its network disconnected (eg wifi turned off) then the connection is formed. If the machine is connected to the corporate network (directly or vpn) then the connection is formed.

However, if the machine is connected to a public wifi (or home network) then the firewall kicks in an kills the connection. In this situation connecting the client to the loopback interface works fine, just not to the home/public interface.

Hope this helps.

<h1>Closed connection in another client</h1>

In my case, the error was:

<pre><code>java.net.SocketException: Software caused connection abort: recv failed
</code></pre>

It was received in eclipse while debugging a java application accessing a H2 database. The source of the error was that I had initially opened the database with SQuirreL to check manually for integrity. I did use the flag to enable multiple connections to the same DB (i.e. <code>AUTO_SERVER=TRUE</code>), so there was no problem connecting to the DB from java.

The error appeared when, after a while --it is a long java process-- I decided to close SQuirreL to free resources. It appears as if SQuirreL were the one "owning" the DB server instance and that it was shut down with the SQuirreL connection.

Restarting the Java application did not yield the error again.

Given this stack trace snippet

<blockquote>
 Caused by: java.net.SocketException:
 Software caused connection abort:
 socket write error &nbsp;at
 java.net.SocketOutputStream.socketWrite0(Native
 Method)
</blockquote>

I tried to answer the following questions:

<ol>
<li>What code is throwing this exception? (JVM?/Tomcat?/My code?)</li>
<li>What causes this exception to be thrown?</li>
</ol>

Regarding #1: 

Sun's JVM source doesn't contain this exact message, but I think the text Software caused connection abort: socket write error is from the native implementation of <code>SocketOutputStream</code>:

<pre><code>private native void socketWrite0(FileDescriptor fd, byte[] b, int off,
 int len) throws IOException;
</code></pre>

Regarding #2

My guess is that it is caused when the client has terminated the connection, before getting the full response (e.g. sent a request, but before getting the full response, it got closed / terminated / offline)

Questions:

<ol>
<li>Are the above assumptions correct (#1 and #2)?</li>
<li>Can this be diffrentiated from the situation: "could not write to the client, due to a network error on the server side"? or would that render the same error message?</li>
<li>And most important: Is there an official document (e.g from Sun) stating the above?</li>
</ol>

I need to have a proof that this stack trace is the socket client's "fault", and there is nothing that the server could have done to avoid it. (except catching the exception, or using a non Sun JVM SocketOutputStream, though both don't really avoid the fact the client has terminated)

Official reasons for "Software caused connection abort: socket write error"

身份验证

数据库

服务器

防火墙

数据流
