I've got the Fileupload and I set this in my WebConfig:
<system.web>
<compilation debug="true" targetFramework="4.0" />
<customErrors mode="Off"/>
<httpRuntime
executionTimeout="110"
maxRequestLength="102400"
requestLengthDiskThreshold="80"
useFullyQualifiedRedirectUrl="false"
minFreeThreads="8"
minLocalRequestFreeThreads="4"
appRequestQueueLimit="5000"
enableKernelOutputCache="true"
enableVersionHeader="true"
requireRootedSaveAsPath="true"
enable="true"
shutdownTimeout="90"
delayNotificationTimeout="5"
waitChangeNotification="0"
maxWaitChangeNotification="0"
enableHeaderChecking="true"
sendCacheControlHeader="true"
apartmentThreading="false" />
</system.web>
that allows me, to upload 100MB files.. maxRequestLength="102400"
Now the problem is, that the site crashes, when uploading b.E a 85MB File.. It stops working on about 70% and I get an Error.. How can I solve this Problem?
