Yep, zip does not have infinite capacity.

It's possible zip is running out of virtual address space and the side
effect is that the I/O fails.

It's easy enough to use the OS/2 trace to watch the I/O done by zip.
Something like:

trace on /b:1024
trace on /n:zip.exe
trace on kernel(fs=pre+post)
zip
trace off
tracefmt

should let you see the failing I/O.

All that says is it's not a file specific failure.

Well you've got a couple of choices. You could grab the source code for
zip and debug the problem and, perhaps develop a patch to overcome the
limitation or you could try a different backup methodology.
