We are experiencing a serious problem with a 1TB filesystem under RH3 kernel 2.4.21-27 on a Bi-xeon DELL PE1750. The disks are HDS 9570V with Qlogic 2312 FC attach.

After slowdown due to excessive IOWAIT and enless  ls commands  in a 560000   inode directory (I know this may sound not reasonable!) ,

 we have done a jfs_fsck who simply destroyed the directory to put it in lost+found.

We are currently restoring it from backups.

Do you think that a bug in JFS could be in cause?

The file system was created in jfs 1.1.2 and we are currently running jfs 1.1.10

Any hint would help.
