mupdate: attempt to delete unknown mailbox

[Andrew Morgan]

I'm getting an interesting log message on my cyrus frontends (v2.2.12) 
when I delete a mailbox on the backend server using a perl script I 
wrote (which uses the IMAP::Admin perl module):

Jun 15 15:28:42 cyrus-fe2 mupdate[9292]: attempt to delete unknown mailbox 
user.testuser

This message appears on both frontend servers.  The mailbox is 
successfully deleted.  Here is the IMAP telemetry log from the deletion 
done by my perl script:

---------- cyrus Thu Jun 15 15:28:37 2006

>1150410517>try OK User logged in
<1150410517<try LIST "" "user.testuser"
>1150410517>* LIST (\HasNoChildren) "." "user.testuser"
try OK Completed (0.000 secs 2 calls)
<1150410517<try SETACL "user.testuser" "cyrus" "c"
>1150410517>try OK Completed
<1150410517<try DELETE "user.testuser"
>1150410517>try OK Completed
<1150410517<try logout
>1150410517>* BYE LOGOUT received
try OK Completed


Here is the IMAP telemetry log when I use cyradm to do the same thing:

---------- cyrus Thu Jun 15 15:35:09 2006

>1150410909>3 OK User logged in
<1150410909<4 RLIST "" ""
>1150410909>* LIST (\Noselect) "." ""
4 OK Completed (0.000 secs 0 calls)
<1150410919<5 RLIST "" user.testuser
>1150410919>* LIST (\HasNoChildren) "." "user.testuser"
5 OK Completed (0.000 secs 2 calls)
<1150410930<6 SETACL user.testuser cyrus c
>1150410930>6 OK Completed
<1150410942<7 DELETE user.testuser
>1150410942>7 OK Completed


I don't see any real differences between the two telemetry logs...  The 
log message only appears when my script does the deletion, not when 
cyradm does the deletion.

Has anyone seen this before or have any ideas what the cause might be?

Thanks,
