Hmmm, this does sound somewhat odd, I found a few reports of people 
using it on data ranging into megabytes without problems.  What version 
of PHP are you using?

Personally I would be looking at a more efficient form of storage for 
the data which would sidestep the problem you are experiencing.

Yeah, serialized data needs to be read as one chunk, you can't just 
split it and read it piece-by-piece.

If you mail me the code that produces the error off-list (zipped 
please!) I'd be glad to check it out for you.
