I'm getting several errors a minute at present on our domino server console along the format of the below:

Database note open error: NT00000422 document in database /notesdata/mail/catfoss/mparker.nsf opened by CN=SERVERNAME/OU=UK-O=OURCOMPANY: Attempt to perform folder operation on non-folder note.

Our BES (v4.1) runs on domino 6.5.5 on Windows Server 2003. This error is generated on a domino 8.0.1 box which is the main domino mailserver for several regions, presumably when the BES server is trying to perform some operation on the user's mailfile.

This combo was working fine for us up til the last week or so when these errors started getting generated. Anyone come across this before or know how to fix this?
