Error description
A JfS2 FS can be marked corrupt when accessing a lot of files(been seen with the use of the find command). This results in fsck needing to be run the next time the FS needs to be mounted. The error report is updated with symbol addresses indicating problem happened with the following stack : diRead+000354 iGet+000DF8 j2_lookup+000428 vnop_lookup+0001D4 lookuppn+000918 statxat+000320 It is caused by accessing stale metadata. It occurs rarely since most of the time the metadata has acceptable data even though it is stale. However when it does not have acceptable data the FS can be marked as corrupt. The fix of the problem avoids stale data from being accessed
