Hi Patrick,
Thank you for responding so quickly. I took your
advice and ran the command you suggested. It seems
that inode_cache seems to continuously grow... as I
watch this command. dentry_cache follows too, but at a
much slower rate. What does this indicate?
Thanks,
- D.
Here is the output from one instance:
Every 1s: sort -nr -k 2 /proc/slabinfo | head -20
