Peter,

Unfortunately that’s an empty set. It seems like the lock_version is constantly 
changing for this record. I’m not sure why.

Hi Patrick,

What does
SELECT * FROM `user` WHERE ((`id` = 113) AND (`lock_version` = 1271));
say?

Hi all,



I’m trying to diagnose and fix a warning I’m seeing in our AS log files every 
12 or 13 seconds:



Got an optimistic locking error when updating user: Attempt to update object 
did not result in a single row modification (SQL: UPDATE `user` SET 
`system_mtime` = '2021-12-02 16:52:37', `user_mtime` = '2021-12-02 16:52:37', 
`lock_version` = 1272 WHERE ((`id` = 113) AND (`lock_version` = 1271)) LIMIT 1)



I can delete the user, but if I remake it with the same username, the warning 
comes back. If I leave the user open for editing, I get the “This record has 
been updated by another user. Please refresh the page to access the latest 
version,” message in the UI.



Any idea how to fix this issue? I’d prefer to be able to keep the username the 
same. I’m not sure why the system thinks there are two different lock versions 
associated with the record.



Thanks,

Patrick Galligan
