We recently found one problem which could affect the size of the inode
cache. It's not exactly a leak, because the resources can still be
reclaimed, but the inodes were filed away in a place where the VM was
least likely to go looking to reclaim them.
Could you "cat /proc/slabinfo" on the affected systems and see what the
inode_cache entry looks like, please?
Cheers,
Stephen
