Coming back to this old issue, https://bugs.internet2.edu/jira/browse/GRP-1725 says "this can happen if two threads add attributes or values at the same time"

I take this to mean that Grouper will not actively prevent multiple values from getting into a single-value-defined attribute.  Are there plans to fix this race-condition bug?

I miss-clicked on the "UiV2Main.miscellaneous" list of functions and clicked on "Instrumentation". I was promptly presented with this error msg. (and nothing else)

"
Error: Attribute is not multi-valued, but has multiple results!
etc:attribute:instrumentationData:instrumentationDataInstanceLastUpdate,
 AttributeAssignValueDelegate[ attributeAssign=AttributeAssign
        [id=0f5b3b35b1764fde9f7a37f9ba7b9831,action="assign,attributeDefName=etc:attribute:instrumentationData:instrumentationDataInstanceLastUpdate,ownerAttributeAssignId=20245cda30f14b7d9ee6197668c50bfe]],
        size: 2,
 Problem calling method instrumentation on edu.internet2.middleware.grouper.grouperUi.serviceLogic.UiV2Admin
"

I understand what the error is saying. However:
        I don't know how the system came to be in this state. ( At this point, I assume due to some automated process that went sideways. )
                Is this a known bug at some patch level? Result of a failed process? (loader job? I2 Instrumentation?)
        I don't know the right way to fix this either.
                Track down where the multiple assignment(s) are remove (one? All?) them?
                Change the attribute to be multi-valued?
                What is the downside to those actions?

If more information is needed then please send gsh/sql commands/UI click paths/files to grep/etc....
        I would be glad to poke around . ( Just give me the right stick to poke with.)  :)

Thanks in advance.
