"Instructions from financial institution" on OSU?

On my OSU over the past few days, I've received in the status box from 
my credit union, the OCEAN CREDIT UNION, the following:

"Instructions from financial institution

OCEAN CREDIT UNION

OCEAN CREDIT UNION accounts can't update right now. We are investigating 
the issue"

But they do seem to be updating, and all the accounts in my account list 
pertaining to this credit union has the recent time date and stamp that 
the OSU was made during the morning.

Anyone have an idea what this might relate to?  I did close a mortgage 
account with them earlier in the week, but took that out of those 
accounts that are eligible for OSU update - in fact, closed the account.

Before I go to the credit union (whom I assume won't have a clue what I 
am talking about), I thought I'd check here first for any ideas.
