This is a pretty ugly problem.
What is happening I think that processes are stuck in uninterruptable sleep. In the kernel log, there's probably something of the sort:
INFO: task java:806296 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
We're finding this happening on NFS backed VM's. Adjusting the mount options to "soft,intr" doesn't really help. In fact, nothing really helps.
The VM cannot be shutdown causing the entire hardware node needing to be rebooted.
We're having this problem on all kernel versions. Not sure if this is related to the network card or something else.
