Same issue here: NFS server running Debian Squeeze amd64 and clients running Ubuntu 12.04 i386 (everything is up-to-date). One 12.04 client can log in just fine; more than one freezes ALL clients which are currently up and causes high (5.0 up from normal 0.5-0.8) load on the NFS server which keeps increasing until the problematic clients are shut down (and just like in the above case, console rarely works, power button or Alt+Printscreen+REISUO is required to switch them off). I am also running OpenLDAP and DHCP there.
We inspected tcpdump logs with Wireshark and found NFS complaining about "utk 10011" error, which I have found no information about whatsoever. >From hours of researching this issue, I'm confident that the problem is in the nfs-common on the client side, since the issue happens no matter whas OS the server is running (10.04, Debian or 12.04 are the ones I've seen mentioned so far). This bug should be given very high priority, since it makes 12.04 clients (and I've read that 11.10 are affected as well) unusable with NFS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1024313 Title: More than one client with nfs home directories will cause freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/1024313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
