I got an exception in cursor-> get() operation. The exception thrown
was "Dbc::get: Cannot allocate memory".

Why is this exception coming?

You are likely running out of locks. You get a more detailed error
message if you enable extended error handling:

Does this reflect any limitation in locking configuration which results
in the above exception?

I would think so:

Quote:

1000 Maximum number of locks possible
1000 Maximum number of lockers possible
1000 Maximum number of lock objects possible
2 Number of current locks
1000 Maximum number of locks at any one time
[...]
1000 Maximum number of lock objects at any one time

You could create a DB_CONFIG file with appropriate settings, for
example:

set_lk_max_locks 30000
set_lk_max_objects 30000

See the documentation for details. You may have to adjust the
settings to your own needs. It's a bit unfortunate that Berkeley DB
cannot dynamically increase the number of locks and lock objects.
