This link seems promising as it explains everything rather nicely, however I still believe the problem is related to nfs

I am also experiencing the same issue, and with NFS actually. Trying to import and unpack Oracle VM template

the log shows stuff like below

Jul 10 20:00:39 oravms kernel: INFO: task nfsd:2415 blocked for more than 120 se
conds.
Jul 10 20:00:39 oravms kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs
" disables this message.
Jul 10 20:00:39 oravms kernel: nfsd D 0000000000000000 0 2415
2 0x00000000


If anybody knows a solution, please!

regards,

raj

Interesting that this has just cropped up for us.

We are running a VMWare server with about 6 VMs, each running Ubuntu 12.04. We've had no problem until last week when I did a restart on two of the systems. For whatever reason, logging in, the systems told us a restart was required. Ever since then, we have these Java errors followed by a call trace:

INFO: task java:1120 blocked for more than 120 seconds.
