There is a source: LaserficheNotification spamming the Application Log with errors, but I don't know what this application is.
There is no service named specifically "LaserficheNotification"
There is no support articles or posts that contain the word "LaserficheNotification"
The Laserfiche Repository logs do not have any associated errors. Usually Laserfiche services do not use the general Application Log in version 10+ so this is concerning. It is also concerning that there is no service or mention of such an application source.
