I am getting this error when I am trying to add content to Umbraco.

This is a production environment, and the issue is urgent.

There is any limitation on how many content items I can build. The site reached about 600 items is that an issue?

This is the error ERROR Umbraco.Web.Editors.ContentController - Unhandled controller exception occurred System.Data.DataException: Record could not be inserted or updated. at Umbraco.Core.Persistence.PetaPocoExtensions.InsertOrUpdate[T](Database db, T poco, String updateCommand, Object updateArgs) at Umbraco.Core.Persistence.Repositories.ContentPreviewRepository1.PersistNewItem(ContentPreviewEntity1 entity) at Umbraco.Core.Persistence.UnitOfWork.ScopeUnitOfWork.Commit(Action1 transactionCompleting) at Umbraco.Core.Services.ContentService.SaveAndPublishDo(IContent content, Int32 userId, Boolean raiseEvents) at Umbraco.Core.Services.ContentService.Umbraco.Core.Services.IContentServiceOperations.SaveAndPublish(IContent content, Int32 userId, Boolean raiseEvents) at Umbraco.Core.Services.ContentService.SaveAndPublishWithStatus(IContent content, Int32 userId, Boolean raiseEvents) at Umbraco.Web.Editors.ContentController.PostSaveInternal(ContentItemSave contentItem, Func2 saveMethod)
