indirectly via SSH from the server, i.e. not logging into the node:
ssh node "ls -lR /files/export > /dev/null"
The command takes up all available memory (near 4Gb) on the node,
while generating hundreds of thousand of slabs (nfs_inode_cache and
dentry_cache) as seen with slabtop. The system is rather plain Ubuntu:
/etc/exports on the server:
/etc/fstab entry on the client node:
home:/files/export /files/export nfs
rw,nosuid,rsize=32768,wsize=32768,tcp 0 0
I'd very much appreciate any pointers on how to treat this problem.
