是什么原因导致我的java.net.SocketException：连接重置？
2022-08-31 07:36:29
我们在日志中看到频繁但间歇性的错误。我们不确定错误的实际来源，以及如何进行调试。java.net.SocketException: Connection resetConnection reset
此问题似乎与我们尝试发送的消息无关。请注意，该消息不是 。connection reset by peer
关于此异常的典型原因是什么，以及我们该如何继续，有什么建议吗？

我们的组件是一个Web应用程序，在Tomcat下运行，它调用发送SMS消息的第三方Web服务，它就是这样发生的。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 );
