Error Failed to generate QVW files.. Exception=System.IO.IOException: The process cannot access the file because..it is being used by another process.

Job run 2 times and fails 8 times intermittently.

We have checked Qlikview servers (QDS,QVS) for any thread being used,but nothing there.

We also asked Fileshare team to check thread if its locked,but its not.

After Temporarily changing "Application Data Folder:" in QMC--System--setup--QDS--General to C: drive(local path),it works

But since its local,will get full in no time.We need to be on FIleshare Application Data Folder:

Have you checked if there is an antivirus running in your company scanning this folder?

Beside any security tools there might be further processes active like shadow copies, indexing and so on. Further a lock is just a flag to the file-metadata and if anything was broken within the process-queue it might be orphaned and be never refreshed until the storage is re-started.

Hello @rashmidehale,

Have a look at the Qlik Support article Reload Task Fail With Error System.IO.IOException The process cannot access the file because it is being used by another process and ensure that the service account has full permissions to the Source Document directory, anti-virus/backup software isn't interfering, and that the system architecture meets the requirements.

Best Regards

I guess this could be the issue.Not with Qlikview but with fileshare server

What we can test/check on fileshare to see whats wrong

Hi @rashmidehale,

You can use Windows sysinternals performance monitoring application. Refer to Qlik Support article How to log CPU, Disk, and memory usage with Microsoft Performance Monitor on a windows 2012 Server (PerfMon).
