site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Hi All, This is perhaps the weirdest Mac problem I've ever dealt with and I think it lives in the kernel and I'm looking for ideas.. here goes... Customer has a server and two clients. All direct attached with clients on their own subnets (they cannot see each other). They run Final Cut Pro. The Server is a Mac Pro. This all started with 10.6.4 on all systems and FCP 7.0 on both systems (fully licensed. no pirating here). The FCP projects are stored on the server. Sometimes, when doing "Save Project As" from FCP on one of the stations, it will claim to save but the resultant file is 0 length. There is no error and no kernel log. When this condition occurs, it will continue. (We will try saving to a local filesystem next) When this happens, the guy will close FCP, open the file from the second station and save it again. Then the first station can save. There are no permissions or acl issues here. Both systems can open all the files. Further, we are quite sure there's no simultaneous opening going on. A dtruss of the issue shows lots of .vol accesses and files with funky hash names (the actual filename is only stat'd a few times) Steps so far: 1. Machines had *identical* host names (Preferences->Sharing). We changed that 2. Upgrade to 10.6.8 everywhere in case of ACL propagation issue 3. Upgrade FCP to 7.0.3 on both systems 4. Check filesystem for corruption (no trouble found) 5. Put clients on a switch (still on different subnets) so they would "see" each other with bon jour. (This would normally have prevented the identical host name thing) My suspicion is that something about the identical host names remains in place. Perhaps there are hashes stored in /.vol that are causing trouble? I'm wondering if someone with AFP/HFS knowledge might know of something here.
