Maximum file limit for rpmbuild

[Marty Ridgeway <mridge50 verizon net>]

I seem to be having a strange problem. I'm building a very large RPM 
file, 10K+ files and the build appears to go along normally and then 
just stops. No error code, no apparent failures, it just stops.

Is there a limit to the number of files RPM can handle?  I can but would 
prefer not to, break up the binaries and build 3-4 RPM files if needed.

Thanks, Marty
