Hello,

This is one of those unreproducable occasional error in the log questions. Hoping maybe someone has encountered it.

We are setting a custom member property and then saving that member. Every so often we see an exception updating the index. Interestingly it's not always the same value in the property type id (the 3rd value in the index). I assume saving the member saves all properties though.

Code:

var member = _memberService.GetByEmail(model.LoginEmail);
member.SetValue(alias, value);
_memberService.Save(member);

Stack Trace:

ERROR Umbraco.Core.Persistence.UmbracoDatabase - Exception (3afecff6).

Has anyone else seen this?
