Was that a one off error, or is it repeatable. If it is repeatable please give the steps to reproduce the effect.

I think that you are running up against a 32bit addressing issue.
Audacity 1.3 can handle files of any size, but Audacity uses shared libraries in the operating system that may not be able to do so. Depending on the sample rate / bit depth / number of tracks, I would guess that your recording is around 4GB in size. The maximum number that can be expressed with 32 bits is about 4 billion
(a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory).
If you are making very long recordings, use "Export Selected" from the File menu to export the recording in chunks that are well below 4GB. Exporting your file as 5 x 1hour sections will probably solve the issue, and will also make processing a lot faster.
