Well that doesn't look good. 100% of the inode cache for jfs are being
used which either means
- there's a memory leak, or
- there's some sort of throttling issue in jfs.
And those objects are consuming ~2.3GB of slab on your 4GB machine and
seems to only have occurred between v3.4.2 to v3.5.3.
It would be interesting to see what kmemleak would tell us.
