java使用commons-fileupload上传文件时报connect reset错误

[sc930524]

服务器是weblogic，双服务器
框架使用的是spring mvc+mybaits
同一表单，不同的数据、文件，有些上传成功，有些会报connect reset错误，而且上传不成功的表单多次尝试仍旧不行

前台表单：
<form id="addInfoForm" class="form-horizontal" role="form" enctype="multipart/form-data" method="post">
<input type="file" name="commentFilePath" id="commentFilePath" style="margin-top:6px;" class="required">
</form>
表单的提交试用ajaxSubmit的post方式

spring配置：
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="60000000"></property>
<property name="defaultEncoding" value="UTF-8"></property>
</bean>

后台报错：
