Nous constatons de fréquentes mais intermittentes java.net.SocketException: Connection reset
erreurs dans nos journaux. Nous ne sommes pas certains de l'endroit où le Connection reset
L'origine de l'erreur et la manière de la déboguer.
Le problème semble ne pas être lié aux messages que nous tentons d'envoyer. Notez que le message est pas connection reset by peer
.
Avez-vous des suggestions sur les causes typiques de cette exception et sur la manière de procéder ?

Notre composant est une application web, fonctionnant sous Tomcat, qui appelle un service web tiers qui envoie des messages SMS, il se trouve que c'est le cas. La ligne de notre code sur laquelle l'exception est levée est la dernière ligne de l'extrait de code ci-dessous.
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 );

Comme vous le voyez dans la pile complète, cela commence par
read
opération . Votre client est parti mais vous essayez de lire à partir de son flux. Voir ma solution ServerSocket stackoverflow.com/a/31741436/413032 .
