On our POA we are seeing some errors that relate to a problem 93 issue,and I was just wanting to get some clarification on what this error means?

Problem 93- Unused blob file (missing trailer): 4CCAE0A5.000
- Blob type unknown, FieldId=0
No further info available for this Blob
- deleting file
Problem 93- Unused blob file (missing trailer): 4CD12D1B.000
- Blob type unknown, FieldId=0
No further info available for this Blob
- deleting file
Problem 93- Unused blob file (missing trailer): 4D057D4C.000
- Blob type unknown, FieldId=0
No further info available for this Blob
- deleting file
Does this mean that it is just deleting the file, and removing a "pointer" from that email message? Is there something in the documentation that would help explain this error? Thank you,
