Remove of supposedly empty directory ... failed: Directory not empty

[Marcus Schopen]

Hi,

today a saw a lot of messages like this in my mail.log (Cyrus 2.4.12)

Sep 23 15:54:04 testserv cyrus/imaps[21530]: Remove of supposedly empty 
directory /var/spool/cyrus/mail/s/user/test/aaa failed: Directory not
empty

Those messages come up when renaming folders using eg. Thunderbird:

- create a folder "aaa"
- create a subfolder within "aaa" called "bbb"
- copy some messages into aaa and bbb folder
- rename "aaa" to "zzz"

And they also came up at daily cyr_expire this morning (delete_mode and
expunge_mode set to delayed):


Sep 23 06:03:39 serv cyrus/cyr_expire[5179]: Remove of supposedly empty
directory /var/spool/cyrus/mail/u/DELETED/user failed: Directory not
empty
Sep 23 06:03:39 serv cyrus/cyr_expire[5179]: Remove of supposedly empty
directory /var/spool/cyrus/mail/u/DELETED failed: Directory not empty

Anything to be worried about?

Ciao
Marcus
