java webservice偶尔会无响应，急～～～

[PowPro]

我用jax-ws开发了一个java webservice。无论是部署在jboss还是tomcat上面，都出现同样的问题，每天都平均会有10次左右的无法响应的错误。由于生产环境的要求，程序是部署在windows2008上，数据库采用了sqlserver2008。各位看一下大概是什么原因。这个webservice的访问量比较高，一天有9000多单的访问次数。每次访问大致会涉及到写数据库、备份本地客户提交的文件、调用另一个webservice以获取回应数据。

程序无响应后，过几秒种再次访问仍然可以响应。只是偶尔访问一次失败，几分钟后日志报了这样的错误。而且特别奇怪的事，出错并不是在高峰的时候，将近一半的出错是在凌晨半夜没什么数据的情况下

好象是客户端与服务端的连接有问题，你可以将有问题的客户端ip收集，看下有没有规律

Caused by: java.net.SocketException: Software caused connection abort: socket write error。 9000次的访问应该不是很大，会出现连接问题一般这么几个情况分析： 1、客户端请求的超时时间小于服务端的处理并且返回响应时间。 2、web服务端操作排队过多，把排队的、并发处理以外的请求拒绝掉了。 3、IO过大，引起负载过高，响应时间加长。 4、要么就是针对特殊客户端有特殊处理引起的。 5、最后无处分析：那可能出现网络的问题。 针对你的问题，我怀疑是第一种情况，因为你的一次请求业务好像比较多，容易引起业务处理时间比较长，你可以试一试？或者第四种情况。
