Subject [jira] [Commented] (FILEUPLOAD-202) org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly
Date Fri, 02 Dec 2011 18:29:39 GMT

    [ https://issues.apache.org/jira/browse/FILEUPLOAD-202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161777#comment-13161777

tina commented on FILEUPLOAD-202:
---------------------------------

It seems the maxThread in resin configuration doesn't work. Because I set it to 256, but when
I run 350 thread, it can still run correctly. Before I thought it is because the first threads
finish quickly, another threads reuse them.But I set the view result in table in Jmeter, and
saw each request sent almost the same time, and the sample time plus the start time is after
other sample's start time. I thought resin should stop processing the request when the number
of threads exceeds the configured maxThread. Do you know the reason why it still can run correctly?
