Hello, 
I deleted some old emails via Move to Trash .... [ i.e. select the emails to
delete then Move to Trash .
At the beginning kmail/akonadi worked fine ... but when I start deleting
hundred of emails ... the process came to a still and I let the laptom over
night to finish the delete .

In the morning the delete was done and the trash folder was empty , then I did
akonadictl fsck 

I got a lot of messages ...
Found unreferenced external file:
/home/<userid>/.local/share/akonadi/file_db_data/11/80611_r0
and that 100 files were moved to lost+found .

Is there any way/proc/etc to get rid of those messages ?

My understanding is that kmail/akonadi  deletes all database records related to
the deleted emails .  Those messages point to an unsynchroned database after
deletion .

Please have a look at this issue and tell me what/how to do to get rid of those
messages .  

Please find below akonadictl fsck output .

Thank you.

Best regards,
Nick
