Hi David, We are now running 2.6.32 - no kslowd issues at all, however during peak times (only ~12Mbps of NFS traffic per box) we get this in dmesg. CacheFiles: I/O Error: Unlink failed FS-Cache: Cache cachefiles stopped due to I/O error Then restart: CacheFiles: File cache on sdb1 unregistering FS-Cache: Withdrawing cache "mycache" FS-Cache: Cache "mycache" added (type cachefiles) CacheFiles: File cache on sdb1 registered Peak period again: CacheFiles: I/O Error: Unlink failed FS-Cache: Cache cachefiles stopped due to I/O error Restart: CacheFiles: File cache on sdb1 unregistering FS-Cache: Withdrawing cache "mycache" FS-Cache: Cache "mycache" added (type cachefiles) CacheFiles: File cache on sdb1 registered Peak period again: CacheFiles: I/O Error: Unlink failed FS-Cache: Cache cachefiles stopped due to I/O error And so on. This is happening on all 10 production VMware guests, running Gentoo on an IBM Bladecenter.

Ah! I see it now. However, it doesn't look like you did: keyctl add user fscache:objlist KB @s before doing: cat /proc/fs/fscache/objects >/tmp/object-list.txt Did you manage to get the keyutils package installed? You could also download: http://people.redhat.com/~dhowells/keyutils/keyutils-1.2.tar.bz2 and try building that. David
