  Hello - I have deployed my application in 2 load balanced servers. The temporary folder is pointing to shared NAS. However the upload to tempo folder fails sporadically. Any idea on why it fails sporadically. thanks

  Hi Balaji,
  
  Do you see any exception reports in the system error log?
  
  We'll appreciate any additional information that might help us with troubleshooting the issue.
  
  How often is this error occurring? Does it occur during high load or randomly?

  Hello balaji ,
  
  We are facing a sporadic issue when using the RadUpload control in our website.
  
  The application is hosted    in a load balanced server and the session is stateless.
  

  This is what is happening. If the user uploads 10 files (then it creates 10 temp files on the server in RadUploadTemp folder.)We have 2 app servers and when the user access the server, it might get connected to appserver1. But there is no guarentee that for all the 10times it tries to access the server, it will always go to appserver1 as they are loadbalanced. The moment it hits appserver2, we get file not found exception. If it always hits appserver1 then all the files will be uploaded successfully
  
  Can you please share how you solved this issue from your end
  
  Thank you
  Regards
  Pankaj

  Hello Pankaj,
  
  To avoid inconsistency of the thread, please let continue our discussion in the support ticket.
  Using a shared folder will resolve the issue. Make sure that your application has a write permissions to that folder.
  
  All the best,
