1.  HELP - I-O and corrupted errors in NAV 2013

GOLD CONTRIBUTOR
Posted 5 days ago
Good morning everyone!

We are having some challenges in NAV 2013 this week that has caused us a lot of downtime and we still are unclear to source of the problem.  Many users are reporting errors that are shown in a 'Microsoft Dynamics NAV' error box.  The errors are:

  • "The file or directory is corrupted and unreadable"
  • "An I/O exception occurred during the operation"

Eventually the transactions will go through, but this has been a struggle for us.  We run in a virtual environment (VMware) using all-flash storage array for the database (Kaminario).  We have tried moving VM hosts and the problem has followed.  We run check disks and did find two DLL's that needed repaired and that seemed to fix the issue, but this morning we had one report of the I/O error again.

I find these error messages vague and unhelpful.   Does anyone have any insight to these errors and a possible root cause?

Many thanks in advance!

Tony

Hello Tony,

Check the Event Viewer on both the NAV application server and the NAV database server. Look under Windows Logs => Application. See if you can find the same error messages appearing in the Application log as shown in the NAV error boxes, and determine which of these servers has the problem.

If you can determine which server has the issue, then proceed to check the System log as well. Look for any yellow or red warnings in the System log. You may find more detail about the issue here.

Also, in moving VM hosts are you still using the same hardware infrastructure? You might consider troubleshooting the hardware layer first. The RAID/disk array controller might be failing. You might have disk issues. Additionally, if you have diagnostic software that can do a memory test, it's good to make sure your memory is free from problems too.

Hi Tony,

We have experienced the I/O error in the past and we use the VM ware as well.
As Alex suggested, the RAID/disk array controller might be failing. You might have disk issues. Additionally, if you have diagnostic software that can do a memory test, it's good to make sure your memory is free from problems too.

Adding more memory has helped us in the past but the usually the real problem is in the hardware so you might wanna run a diagnostics on that.

Thanks,
Meenakshi

​What Alex said. Definitely make sure all your backups are up and running, and make sure your hardware isn't crapping out.

Make sure you're running all your daily and weekly SQL tasks, along with the backups, to make sure the database itself is not corrupted.

Thank you @Alex A, @Meenakshi Singh and @Val Gameiro for your inputs.  After focusing on the hardware, we determined one of our VM hosts crashing led to 2 corrupt DLLs.  Running 'Chkdsk' noted them and repaired them.  Then we rebooted, started all NAV services and (fingers crossed) have been ok since that time.

My hope is that Microsoft can improve their system error messaging to help guide users and admins.  It doesn't appear there was any data corruption as a result of what happened, either.

Thanks again to all,

Tony​​​​

From your mouth to Microsoft's ears! Who knows -- given that they're building Tenerife out to be both SaaS and on-prem for their own cloud-version sake they might improve the error handling and messaging, which would trickle into the on-prem versions. *fingers crossed*

I'm not sure what your particular situation is, but I have received the "I/O exception error" when a file is trying to be written but is locked. This usually happens in a report with Excel or a temporary file when printing. If users are getting this error on a particular report, the issue might be files involved with the report.

I realize that is vague, but the error message itself is a bit vague.
