Receiving Duplicate error on alf_child_assoc

Hoping for some input.
in my logs I find this error occurring 100's of times.

Then I looked into the table, I don't find that key in parent_node_id.
I do find several 637884 but the field is 20 char so this left me confused.

any idea what is causing this and how to resolve?

Re: Receiving Duplicate error on alf_child_assoc

The issue is not with the parent_node_Id column, but with the unique index of the same name on that column and a slew of other colums. Some of the dashes in the '637884-33-3698713139-feedbacksummary_0dba58dd-8681-4a0a-99e0-159' key value link the values of different columns. So you have parent_node_id 637884, type_qname_id 33, child_node_name_crc 3698713139, child_node_name feedbacksummary_0dba58dd-8681-4a0a-99e0-159. Somehow you have a conflict with another row in the alf_child_assoc table with the same values for these columns.

Re: Receiving Duplicate error on alf_child_assoc

Good Morning,

I have the same issue since 27.Aug.2018 02:55:56 ...

And I just cannot explain how this could happen.

The system runs now for more than a year without any error message.

The error came all of a sudden and repeats from since every some 5 minutes.

Any idea how I can get rid of it?

Thanks for helping,

Martin

Re: Receiving Duplicate error on alf_child_assoc

I never really resolved this, I changed the id number, thus it was unique and the error stopped. 
never figured out why I got it or what it's was trying to get.

Thanks for helping.

I just wanted to change this specific data set, but then I found out, that the error has suddenly stopped without any input.

It has gone like it has been appearing ...
