Subject: Recovering invalid records

Hello,

I have mbbi records which are using stream/asyn.
For some reason my records become invalid after some time.
SCAN is passive and triggered through FLNK of the associated mbbo record.

Is there a way to recover from an invalid record?
What turns it into invalid in the first place?
(Well, I could do some testing to answer that latter question...)

Thank you in advance,
