Patrick,

What is the DBMS that you are using? Since the image are unmanaged (file system) the DBMS should face the same file-handles limitation, no? Anyway, do you really need to have all 2254 files opened at the same time? Just curiosity.

Best regards,

Ivan

If it is not a limit in the library, do you have any ideas?

Could you be running out of file handles?

By default, at least on my Ubuntu box, there is a maximum of 1024 file
handles per user process. If you're on Linux you could find out the
limit on your system with 'ulimit -a'.

I support Daniel's assumption.
On my Mac OS X 10.5 (Power PC) it's set to 256.
So, it varies significantly across operating systems.

Best regards,
