Kannel SVN: Messages get stuck in queue

I use 6 load-balanced connections, all are bind_receiver with the same SMSC
ID (XXX) 3 of them accept-smsc=XXX and the rest accept-smsc=XXX1 (I added
XXX1 as a dummy smsc to prevent sending from this smsc connection)

at a certain moment sending over these connections stopped and my MTs get
stuck in my DB, when I checked I saw the following infinite loop in kannel
log file:

note that at that moment my client was stopped and no http requests were
sent to smsbox, I found that the queue is full of the smsc connections and
the store directories contain (100) messages!

(1) Why these messages get re-queued infinitely? Whats wrong?
(2) When I checked the SMPP connection log, the connection was idle and only
enquire_link and enquire_link_resp appear in the log
(3) since there are 3 connection that accepts XXX, why there are only 100
messages in the queue? there should be 300, right?

Note: I have compared the contents of these messages in the queue to valid
messages (sent successfully) and didn't notice any structure differences!

However, when I restart the SMSC connections, everything go fine since these
messages get discarded


Does anybody has this case? thanks
