Symptoms

Oracle Linux that installed "McAfee Linux Shield", hung up the system after mount to NFS.

Check the lshook module (The module is provided by McAfee, hence a 3rd party to Oracle Linux) on the Call stack in /var/log/messages like blow, please contact McAfee for further diagnosis.

 

McAfee will suggest to use NFSv3 instead of NFSv4. But some environment, we could not clear the problem even using NFSv3. Under these circumstances, we could not get the vmcore with NMI, because there were no CPU resource for processing the interrupt.
