Hi Jan, Martin, & Patrick,

I think I found the bug here and its really simple.  Basically, there
should be a close for every file opened or we eventually run out of
file IDs within the MNC lookup tables.  Looking at
MITgcm/pkg/cd_code/cd_code_write_pickup.F I see the line:

        CALL MNC_FILE_CLOSE_ALL_MATCHING(fn, myThid)

which is apparently missing from the corresponding set of calls in
MITgcm/model/src/write_pickup.F.

So I've added the line locally and am testing it right now.  If there
are no apparent problems, a check-in will follow shortly.

Hope that helps!

Ed
