Which version of the OMERO client and server are you using?

If the ome.tiff is a BigTIFF, then the maximum size will be the maximum
size of BigTIFF (2^64). If it's not BigTIFF, then it will be the normal
2^32 (4 GiB).
Is your 740,000 frame tiff series a single file, or multiple files? Is
it in any particular format which bioformats knows about ("showinf" will
tell you)? If it's multiple files, are these structured in any
particular way (e.g. naming scheme) to give information about the
Can you reproduce the failure with a smaller series?
We can certainly look at why the series fails to import, but we'll need
a copy of the original data for that, and 90GB is quite large.

This is a known bug; we currently don't automatically enable BigTIFF
writing when the data is too big for normal TIFF, and we don't provide a
means to enable it by hand.
You can certainly convert using "bfconvert" and its "-bigtiff" option as
a workaround for the time being.

I'm afraid there's not much information to go on here. We'll need some
more detail about exactly what you observed and what you expected. If
you wish to provide us with an example, you can zip the data up and
upload it using http://qa.openmicroscopy.org.uk/qa/upload/ and we can
look at it in more detail.
