Hi,

On one of our websites running v7.3.8 we regularly see the process using a large amount of memory, sometimes over 4 gig. It is quite a big site, but that amount of memory usage seems excessive.

Looking in the logs the only errors I regularly see are for SEO Checker and Vorto.

The errors are:

2016-06-23 14:10:45,328 [P8028/D6/T119] ERROR Our.Umbraco.Vorto.Web.PropertyEditors.VortoPropertyEditor+VortoPropertyValueEditor - Error converting DB value to Editor
System.NullReferenceException: Object reference not set to an instance of an object.
at Our.Umbraco.Vorto.Web.PropertyEditors.VortoPropertyEditor.VortoPropertyValueEditor.ConvertDbToEditor(Property property, PropertyType propertyType, IDataTypeService dataTypeService)

and

2016-06-23 15:06:42,355 [P8028/D6/T29] ERROR SEOChecker.HttpModules.UrlModule - SEOChecker: Error in PageNotFound Module
System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

   at SEOChecker.Core.Providers.NotFoundProviders.SEONotFoundProviders.GetResultByUri(Uri uri)
   at SEOChecker.HttpModules.UrlModule.(Object , EventArgs )

Has anyone else seen this happen?

Thanks

Steve
