是什么导致我的 java.net. SocketException: 连接重置？
我们在日志中看到频繁但间歇性的 java.net.SocketException: Connection reset错误。我们不能确定 Connection reset错误实际上是从哪里来的，以及如何进行调试。
该问题似乎与我们试图发送的消息无关。
注意，消息是 没有 connection reset by peer。
对于这种异常的典型原因可能是什么，以及我们应该如何处理，有什么建议吗？
下面是一个有代表性的堆栈跟踪(com.companyname.mtix.sms是我们的组件) :

我们的组件是一个运行在 Tomcat 下的 Web 应用程序，它调用发送 SMS 消息的第三方 Web 服务。从中引发异常的代码行是下面代码片段中的最后一行。
String aggregatorResponse = null;
HttpClient httpClient = prepareHttpClient( username, password );
PostMethod postMethod = preparePostMethod( textUrl );
try {
SybaseTextMessageBuilder builder = new SybaseTextMessageBuilder();
URL notifyUrl = buildNotificationUrl( textMessage, codeSetManager );
String smsRequestDocument = builder.buildTextMessage( textMessage, notifyUrl );
LOG.debug( "Sybase MT document created as: \n" + smsRequestDocument );
postMethod.setRequestEntity( new StringRequestEntity( smsRequestDocument ) );
LOG.debug( "commiting SMS to aggregator: " + textMessage.toString() );
int httpStatus = httpClient.executeMethod( postMethod );
