I have found those two entries and they are less than two minutes apart.

I noticed that the following entries where sitting between them:
 

05/20/24-11:05:47:140 (7248) 1 [Utility.Event] Backup.General.ExternalFreeze: Warning, d:\intersystems\healthconnect\mgr\irislocaldata\ is not being journalled
05/20/24-11:05:47:140 (7248) 1 [Utility.Event] Backup.General.ExternalFreeze: Warning, d:\intersystems\healthconnect\mgr\hslib\ is not being journalled

I don't know why they weren't journalled, but when I set to be journalled, the error I initially reported has since disappeared.

Thanks for your comment, it help me solve my problem.
