Stuck messages at BPM

Hi guys,

I’ve a BPM that is receiving 4 different files, each one is sent by a File Sender interface. These files are all correlated by a common key field and everything runs perfectly until one of them starts sending more than one message instance… I mean, one of the sender file adapter are limited to 1000 records per message and of course this will generate two messages instances if XI receives a file with 1001 records. So, the problem is: only the first message, a chuck with 1000 records is sent by my BPM the other one stays stopped with a green flag, like scheduled for later process… How can I make it works for all instaces from the same message type?

Should it be a regular behavior, some kind of limitation?

Thanks in advance,

Ricardo.
