Moshe> The kernel with RHEL 3.8 is 2.4.21-47.ELsmp. That's a significant jump in functionality. I don't think 2.4 had any memory mapped functionality at all. If 2.6.18 has any (redhat likes to backport all sorts of things), the question becomes... does it work? 2.6.18 is 5 years old. My suggestion is to turn off (in the source code), any of the mmap functionality, or at least printf() what is being used. I would also wonder if you are doing technology renewal, why you are stopping at Centos 5, rather than 6 (or higher?) with a linux 3.0 kernel... -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr () sandelman ottawa on ca http://www.sandelman.ottawa.on.ca/ |device driver[ Kyoto Plus: watch the video <http://www.youtube.com/watch?v=kzx1ycLXQSE> then sign the petition.
