well my only comment based on working with the freebsd nfs code for the last 4 or so years is that mmap'ed files are marginal. Simple things like msync don't work correctly in 3.0-current. The problems are partly bugs and partly architectural. You've found one rule for getting good stat data -- open the file. But a simpler rule for mmap'ed files: avoid over NFS. ron Ron Minnich |"Using Windows NT, which is known to have some rminnich@sarnoff.com | failure modes, on a warship is similar to hoping (609)-734-3120 | that luck will be in our favor"- A.
