Event ID 6838: Failed to recall a Saveset from its Collection

Hi all,

I'm getting this error (6838) from time to time:

Failed to recall a Saveset from its Collection.

Is there any way to know wich mailxbox is involve? What can I do with it? Am I loosing data? No user has called saying is having problems opening archived emails.

I'm also getting theses errors when exporting some mailbox  archives to a PST and when rebuilding indexes.

Thanks in advanced and best regards.
