Subject: [BUG] kmem_cache_create: duplicate cache nfsd4_stateowners
Date: Mon, 17 Jul 2006 12:51:42 +0300 [thread overview]
Message-ID: <44BB5DAE.7080007@plutohome.com> (raw)
I couldn't get the nfs server running on one of my machine, and by
looking in dmesg, seams like there is a kernel problem. I use a
2.6.16.20 vanilla kernel but i remember getting the same error with a
2.6.17 kernel too, a week ago when trying to run rpc.nfsd. I couldn't
get any pattern to reproduce it yet but i got it more then once. If you
need any other info, please contact me.
