  Hi, can you please confirm that there is a situation as described in this answer or not?

  Hi, it seems like very similar case as I was not getting this error earlier. It is happening when load is high, also in my case too we have upgraded the version last year, but my class structure is below

      public class PatientPhoneNumber_TR : FullAuditedAggregateRoot<Guid>
      {
      [CanBeNull]
      public virtual string PhoneNumber { get; set; }
      public long? PhoneTypeId { get; set; }
      public long? EquipmentTypeId { get; set; }
      public long? PatientId { get; set; }
      
        public PatientPhoneNumber_TR()
      {
  
      }
  
      public PatientPhoneNumber_TR(Guid id, string phoneNumber)
      {
          Id = id;
          Check.Length(phoneNumber, nameof(phoneNumber), PatientPhoneNumber_TRConsts.PhoneNumberMaxLength, 0);
          PhoneNumber = phoneNumber;
      }
  }  
  

  I'm using parent's id as FK in child table.

  Please let me know what can I do to fix it?

  I have noticed same issue on save token too (screenshot of error is attached below), please help to fix both.

  Hi, can you override the HandlePropertiesBeforeSave in your dbcontext class as below and try it, please?

      protected override void HandlePropertiesBeforeSave()
      {
          var entries = ChangeTracker.Entries().ToList();
          foreach (var entry in entries)
          {
              HandleExtraPropertiesOnSave(entry);
  
              if (entry.State.IsIn(EntityState.Modified, EntityState.Deleted))
              {
                  UpdateConcurrencyStamp(entry);
              }
          }
  
          foreach (var entry in AbpEfCoreNavigationHelper.GetChangedEntityEntries().Where(x => x.State == EntityState.Unchanged))
          {
              UpdateConcurrencyStamp(entry);
          }
      }
  

  Please let me know if it fixes your problem or not.

  protected override void HandlePropertiesBeforeSave()
  {
  var entries = ChangeTracker.Entries().ToList();
  foreach (var entry in entries)
  {
  HandleExtraPropertiesOnSave(entry);

          if (entry.State.IsIn(EntityState.Modified, EntityState.Deleted)) 
          { 
              UpdateConcurrencyStamp(entry); 
          } 
      } 
  
      foreach (var entry in AbpEfCoreNavigationHelper.GetChangedEntityEntries().Where(x => x.State == EntityState.Unchanged)) 
      { 
          UpdateConcurrencyStamp(entry); 
      } 
  } 
  

  Hi, as it is override in dbcontext class, can you please confirm if it can impact the performance?

  Hi, it should not impact performance. In our current version, this code is already implemented in the AbpDbContext implementation (I mean in v9.0+).
