asterisk users - May 2015 - Realtime peers, mailbox and MWI problem

Hello,
I am facing a problem I can't understand. I have several realtime SIP peers
and from time to time, the mailbox field is not loaded in asterisk memory.
The mailbox field is correctly populated in the database, but often, after
an asterisk restart, the mailbox is not associated to the peer (just to
understand, if I run "sip show peer 104-TEST", I see the Mailbox
empty. If
I run the "sip show subscriptiona", I don't see any subscription
for the
MWI but only for the BLF.

Is there anyone facing the same problem? How have you solved it?
