IOUserClient size limit?

I am seeing a kIOReturnIPCError form an IOUserClient down call (i.e.
from my app into the kernel) when I have a structure that is over 4K
(4096) bytes in size.
Is this a hard limit? Can I change this limit? I have some I/O through
the user client that I would like to take a larger buffer (16K).
Thanks for any tips,
...Duane
