Due to a question in SE I once again checked the file size limit in Mathematica  9.

data = ConstantArray[Image[ConstantArray[4095, {1024, 1024}], "Bit16"], 1500];
Export["C:\\Users\\stelzer\\Desktop\\test.tif", data, "TIFF"];

dataIn = Import["C:\\Users\\stelzer\\Desktop\\test.tif", "TIFF"];



As you can see, no error message and only 1023 files are written.

The situation is even worse when the file size is larger than 2GByte, which we generate regularly with our instruments, and I try to read it.  Mathematica will not produce an error message and will only return the first image!

I use Mathematica 9, Windows 7-64bit, XEON, 96GByte of RAM, ... so not a system you would expect to have problems with.

The suggestion to raise the memory limit:

ReinstallJava[JVMArguments -> "-Xmx6000m"]

Has not changed anything.  I was also wondering if BigTIFF has been (will be?) implemented.
