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. -- Matt Vander Werf HPC System Administrator University of Notre Dame Center for Research Computing - Union Station 506 W.
