Hi all, we get some problems with sharing mailbox between users. when we share something the dovecot-acl file is updated, but the shared-mailboxes.db file is not created nor updated. Even if we create the file and set permission to 777...

strangely the debug log gives :

2024-02-05 09:29:04 imap(xxxxxx)<13741><SA8qQZ4QBIsKDMcL>: Debug: dict(file): dict created (uri=file:/tmp/shared-mailboxes.db, base_dir=/var/run/dovecot) 2024-02-05 09:29:04 imap(xxxxxx)<13741><SA8qQZ4QBIsKDMcL>: Debug: open(/proc/self/io) failed: Permission denied

we don't understand why we get this kind of message. we search on this mailing list without any clean explaination. we expect a bug somewhere..

any ideas ?

system is : debian 12 dovecot 2.3.19.1 (9b53102964)
