Serious ext2fs problem

I think there is a bug in ext2fs. I have a news server that has a DPT
3224 RAID adapter with a 10G RAID 0 array attached. I am running RedHat
4.0, Linux 2.0.27, and INN 1.4unoff4. I also have applied the "noatime"
patch to the kernel, and mount the news spool with the noatime option.
>From time to time, INN will think the disk is full because it gets an
error trying to write. The kernel log has lines like:

EXT2-fs error (device 08:31): ext2_new_block: Free blocks count corrupted for block group 546

in it when this happens (device 8:31 is /dev/sdd1, which is the RAID
disk). I have shutdown INN, unmounted the disk, and run fsck on it, but
that never finds any errors. I also re-made the filesystem on it once,
and that seemed to help for a while, but now I am getting errors again,
and fsck won't fix them.

Two questions:
1) How can I fix the filesystem?
2) How can I fix the system so this doesn't happen?

Is there a problem with the noatime patch that could cause this? I can
email the patch to anyone who wants to see it.
