File write failed: System.IO.IOException: Cannot create a file when that file already exists.

I get this error on occasion, was wondering if anyone else sees it and possible reasons why it occurs?

File write failed: System.IO.IOException: Cannot create a file when that file already exists.

Thanks,

Michael

Have you tried disabling UAC (User Access Control)?

Tried it, but still happened

Anyone else ever see this error? Would like to make them go away if possible, they appear fairly regularly but also fairly randomly.

I'm also having the same error, it also appearing randomly!

I'm using V10 SR4, Enterprise with Publisher.

I have more than 10 apps running, and this problem only happenning in one of the QVW.

No idea what's the root cause since there's not much information in the task log.

Re: File write failed: System.IO.IOException: Cannot create a file when that file already exists.

I found that the QVW which has the random IO exception is distributing to a network drive which looks like this:

\\cnhkgqlv031prd\d$\QlikViewDestination

The destination is actually same location as my publisher, so I changed the destination to D:\QlikViewDestination instead of \\cnhkgqlv031prd\d$\QlikViewDestination

I'm not sure whether it will solve the IO problem (I need to let it run for few days to see the result), but I believe it will because my other apps are distributing directly to D:\ drive path and have never had the IO problem.

Hope this helps

Does this happen all the time? Are you running any type of backup or antivirus that could have the file open and locked?

mellerbeck — Mon, 25 Mar 2013 14:19:06 GMT

We have a fair amount of reloads that happen every five minutes. This error will occur once or twice a day out of thousands of runs. No backup or antivirus is running. The publisher is writing to local disk

I would check the OS system and application logs to see if they show any errors or problems around the the time the QV error happens.

Did anybody find a solution for this issue. We have the same problem for 3 weeks coming randomly at two applications.

Any news around this issue? I have experienced the same at random times

I deleted the associated .old file and .shared file and this resolved the issue

I also helped

We had a similar issue where none of the usual solutions for I/O errors seemed to help. The app would load normally when reloaded manually, but not when a reload was triggered via QMC. Didn't even cross my mind it could be the .SHARED and .OLDFILE in the same folder. These files probably became corrupt when the server crashed during a scheduled reload of the app, so it's purely coincidental that it was this particular application that was affected.

I moved the files to another folder and the app now reloads normally via QMC.

To solve the problem, I copied qvw to another folder and created a new task. It ran normally, with no errors. I then copied all the files (.qvw, .log, .Meta, .TShared) and replaced with the originals.
I ran the qvw again that was in error and worked.
