ArcGIS Feature Service Add/Delete/Updating

[BrianBorg1]

We are facing an issue with all our feature services.  We are using rest api to update/edit the features and randomly an error is being trigerred :

Another application is currently editing the version. [dbo.DEFAULT]

Or

Unable to complete operation.-Lock request conflicts with an established lock [dbo.DEFAULT]

This layer is only being used from the web application we have developed and all updates are sent via the rest api.

Any solutions please

Hi Brian,

Is your feature class registered as versioned?  If not, and you wish not to version the feature class, you may want to consider reducing the maximum number of instances for the service to 1 to test whether or not the conflict is being caused by two instances trying to write to the base table at the same time.

It is not versioned.  Tomorrow I'll reduce the max. number of instances to 1 and test again.
