Work notes and Additional comments being Duplicated

[Ross Walker]

This is in particular to Incidents
i have had reports thats some work notes when added by users of resolver groups is being duplicated upto 5 times

all of these are timed with 1 second between the first and the last one
and some additional comments are also duplicating

these are timed about 1 second apart
i have checked that there are no BR with current.update()
Also when i look at the reported duplication as Admin i cannot see it (there is no duplication for me
but when i impersonate the user i can see the duplication

i cannot figure out what is causing this

Same thing here, but in the RITM.
In my case, the issue has started to appear after the Yokohama Patch 5 update.

Additional comments and work notes are duplicated only through the "Update record" action (directly in the workflow). If I use the same action through a subflow, it's working very well.

EDIT - Potential issue recognized by ServiceNow....

There's a KB open (for internal and customers) that might be related to this issue: 

KB1706740 - Duplicate comments and work notes are observed in the Activity stream intermittently

------ 

I'm also experiencing this issue, only with Incidents. It's only happening on work notes and additional comments, I haven't seen it happen on other fields. 

There are no business rules updating the current record (or any gliderecord updates on incident for that matter)

I'm also seeing in the record history the duplicated record, with an empty Type, an Update number of 0, a Record internal checkpoint of 0 and an Audit sysid of 0
