Check whether `status` column of `job` table is a primary key. If yes -- make it not a primary key. `id` column should be a primary key.

[khopper]

no the status column is not primary. What is next?

[yuri]

Check whether IDX_JOB_STATUS index is unique. It should not be unique.

I can't send emails from aany workflow rules or via the stream when tagging anyone.
Should I just delete every record with this ID?
I also can't find anything in relation to this: key 'IDX_FBD8E0F8A71ECAB0'

[yuri]

It seems something happened with your environment. Did you upgrade anything apart from crm?

You can delete. But I think the problem will appear again.

[khopper]

No, I did not upgrade anything else.

[khopper]

I managed to resolve this by setting and saving the `status` column as primary key and then undoing that change to the table `job`.
