EV10 Placeholder migration - process randomly stops with Error: Enterprise Vault File Placeholder Service not available while processing item

Hi,

We are migrating some placeholders from one volume to another using FSAUtility -pm option

However the process randomly stops with the following error

Error: Enterprise Vault File Placeholder Service not available while processing item \\?\UNC\server.domain.local\archive\file.jpg

Placeholder service is running fine. No errors on EV Server or File server.

Then if we stop the command and run again it allows us to restart the process.

Any idea?

Many Thanks
