http://issues.apache.org/bugzilla/show_bug.cgi?id=37335 Summary: Connection reset by peer: socket write error / Error 500 when uploading a file in Bb 6.2.2 Product: Tomcat 4 Version: Unknown Platform: PC OS/Version: Windows Server 2003 Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] We have a Windows 2003 cluster config , SQL Server 2K and using Tomcat 4. Every now again (about 50 times a day) when an instructor tries to upload a file in Blackboard 6.2.2 we get a Error 500 in IE Explorer 6. Closing down the browser and trying again usually works but sometimes the error persists. We have opened a ticket with Bb but have found out the it's usually quicker to get a solution here. I have replicated part of Tomcat's log below. TIA.
