We have a problem with HP-UX 10.20 clients. Occasionally they stop getting NFS updates from our NAC servers. For instance, you might create a file, but when you attempt do an "ls" on the file it does not appear. But if you log into another system and do an "ls" it is there. The only solution we have found is to reboot the HP.
HP is no help. Their tech support continues it's downward spiral.
At one point a few years ago we had the exact same problem with HP's and solved it by installing 4 or 5 patches. It was just dumb blind luck that I happened upon an HP tech who knew what he was doing. Now those patches are out of date, and the problem has popped up again.
My hope is that someone on the list knows about this problem and can give me a list of patches they installed to fix it. Any input would be most appreciated.
Thanks, Graham

I believe the problem lies in caching the directory contents. This isn't a problem just for HP. Consider the example below acquired from two different Sun machines looking at the same NFS filesystem. Yes, contents are similar, but look at the modification dates:
