dovecot - Jul 2011 - Many "Error: Corrupted index cache file /XXX/dovecot.index.cache: invalid record size"

Hi all,

I just joigned this list, so I'm sorry if this problem has already been 
reported.

I'm running Dovecot 2.0.13 on many servers, one for POP/IMAP access, 
others for LDA, others for authentification only, etc.

All servers are accessing a shared file system, based on MooseFS 
(www.moosefs.org). The FS is mounted using FUSE.

All my Dovecot servers have this configuration :

mail_fsync = always
mail_nfs_index = yes
mail_nfs_storage = yes
mmap_disable = yes

(as adviced for NFS installation).

But I'm still getting errors like this in POP/IMAP logs :
Error: Corrupted index cache file 
/my_moosefs_fs/domain/user/indexes/.INBOX/dovecot.index.cache: invalid 
record size

Sometimes my Dovecot LDA repairs these files, but then it happens again...

All my servers are running Debian 6 over KVM virtualization.

Have you ever encountered this ? Do you think this is a Dovecot problem 
or MooseFS problem ?

Thank you a lot for your answers.

No one has any idea of what happens ?

I forgot to say that mailboxes are MailDir format.
