saving the oddbdatabase to a file

saving the oddbdatabase to a file
we created the database and added many entities to it. for example say around 90000 block entities with each block having some 20 tag attributes. while trying to save the file, we are getting an error "insufficient memory to perform operation.", on a machine with 512mb ram and 3gb of disk space available and the file it created till that time is around 3kb. but if i do the same thing on a machine with 1gb ram and with more than 10gb space, its able to create successfully with the size of 287mb.
i am using the dwgdirect 1.11 version.
1. is there any limitation in number entities, or block entities or size of the oddbdatabase object?
2. is there any way i can save to the file as soon as i write an entity to oddbdatabase, but every time only the new entity should get saved?
are we doing any thing wrong? please suggest a way to use dwgdirect in more performent way.
thanks & regards,
hari @ intergraph

i think you are doing all right and the problem is related to computer memory size. you can try to check the size of the virtual memory paging file and increase it if possible.
unfortunately, dd supports only full saving of database (incremental saving is not implemented yet).
you can try to implement a paging of database objects (description is placed in "paging support" section of dwgdirect developer's guide).

we have no firm plans (schedule) for implementing incremental saving yet.
