Error in communication with MSAccess

I have an Access DB consisting of both Access tables and tables linked to a
PG backend.
When trying to open a large table from the backend, MSAccess freezes with
"ODBC call failed".
>From that moment on the Access session keeps giving this message any time
and ODBC open is attempted. If closed and re-opened, Access can open the
small tables again. Of course the large table cannot be opened.
I attach the relevant part of the log. I guess the relevant line is
"errmsg='Out of memory while reading tuples.'
What can I do? I need to run MSAccess queries that return large amounts of
data and open large tables.

Thank you all.
