ext3 IIRC correctly was still listed as experimental in the 2.4.18 kernel,
there was a bug which could be related to this that I think I read about on the
ext3 mailing list. 

I once saw another system exhibit similar behaviour when a project was 
approaching deadline, a workstation with a large partition of data (100GB+) 
suddenly disappeared which had a very large amount of work in progress on it. 
The user had a few terminals open which were cd'ed into directories on the 
disk which also gave nothing when typing ls, and then doing a cd .. and a ls 
also resulting in nothing. Eventually when I ran out of ideas of what to do 
with the system up I rebooted (of course very frightened that I was going to 
have to tell someone that lots of the data may have gone) it and mounted the 
disk as ext2 ro, ext3 ro and found all of the data was there and complete, 
fsck said the disk was clean and found no errors, after that I just brought 
the system back up and everything seemed fine.

What I did do was upgrade the machine in question to 2.4.19 and never saw this
behaviour again.
