This is the same problem that drew me to this site.
I'm serving about 8 Macs off FileMaker Pro 5.0v3. The server is a 7200/90 with additional RAM and a large HD with over 50% free. All of our office machines are running 9.0.4 with the exception of two old clones running 8.6 and a Titanium G4 PowerBook running 9.1. The office network is 10BaseT Ethernet. (It would be 100, but our ISDN modem (which also provides some hub duties) only has 10BaseT capabilities.)
I'm actually serving three multi-user databases from the 7200, but only one is complaining, and it's doing so frequently. The database is about 8000 records in size, and I'm beginning to fear that we are losing the occasional record due to this problem.
Norton Utilities v5 finds nothing wrong with the server's HD, and the problem repeats itself when the file is moved to another machine. The problem seems to be more frequent during heavy access by many users, or when users simply leave the database open on their machines for long periods of time with no use.
I have the sinking feeling that the file itself is damaged in a way that Recovery won't help (it's been tried) and that I will need to export the records and re-create the database from scratch. I have been hoping, however, that that wouldn't be necessary.
Any ideas?
