Hi Ben,

Following
https://unix.stackexchange.com/questions/17936/setting-proc-sys-vm-drop-caches-to-clear-cache,
I dropped the pagecache (echo 1 > /proc/sys/vm/drop_caches) and that didn't
make any difference. I then freed the dentries and inodes (echo 2 >
/proc/sys/vm/drop_caches) and that didn't make any difference either.

Let me know if there's anything else we could try.

Thanks.
