Hi,

What version of Firebird(Classic, SuperClassic, SuperServer or Embedded)?  

What is the page cache/buffers(run "GSTAT -H" on the database)?

Is it your application that is returning the our of memory error?  Because for a 32-bit application, there is a 2GB memory limit, and if all those 13,000 images are loaded in memory within your application, that is most likely the problem.  And, a 64-bit application doesn't have that limitation.  Also, NTFS is a 64-bit filesystem(even for 32-bit applications), so the 2GB limit doesn't exist, it's above the TeraByte for a single file(but still depends on the size limit of the drive).

Also, we do have customers that have databases that are over 20GB, with approximately 75% of the data being images.  And, that was with Firebird 1.5 32-bit on NTFS, now they are all on Firebird 2.5.3 64-bit.
