Failed to lock mailbox

Hello all,

In mailbox.log, i see a lot of errors :

2013-08-12 07:58:14,382 ERROR [ZxBackup Thread] [] mailbox - Failed to lock mailbox
Lock Owner - xxx@domain.com BB24EF6130 prio=5 id=46190 state=BLOCKED

And after :

2013-08-12 07:58:14,384 WARN  [ZxBackup Thread] [] mailbox - transaction canceled because of lock failure
2013-08-12 07:58:14,384 WARN  [ZxBackup Thread] [] extensions - ZxBackup Thread: com.zimbra.cs.mailbox.MailboxLock$LockFailedException: timeout

Any ideas to fix it ? zmfixperms ?

Thanks !
