Serious filesystem problem (FreeBSD 4.8)

We have a fileserver, an Adaptec 3410S RAID card and
a RAID 01 partition that we use for network storage. It's shared
with NFS and SMB.

A directory that's being shared to an SMB client, has lately
encountered many weird problems.

Suddenly files/directories turn into something similar to this:

# ls -l
drwxr-xr-x  20788 administrator  administrator  7440289925196497251 Sep
11  2004 brokendir

# rm -rf aa
rm: aa: Directory not empty
# ls -la brokendir

Some directories/files are broken like this:

# du -sh some_dir/
du: fts_read: No such file or directory
# cd some_dir/
some_dir# find .
find: fts_read: No such file or directory

The worst thing is, more and more files and directories become corrupt,
albeit not very often.

What should we do? I have attached dmesg output in this mail.
We use Samba Version 2.2.6pre2.  

One thing definately worth mentioning is:  These problems began
occurring a week ago, when one of the disks in the RAID 01 setup
failed.  We simply inserted a new disk, and had it rebuilt, the 
Adaptec Storage Manager Pro  reports healthy disks... And the
other directories in the RAID 01 partition, are also working fine.

Anyone encountered something similar?
