 kernel:BUG: soft lockup - CPU#0 stuck for 24s! [watchdog/0:14]

 Reason:

 Many Linux kernels have a soft lockup watchdog thread, and report soft lockup messages if that watchdog thread does not get scheduled for more than 10 seconds. 
 On a physical host, a soft lockup message generally indicates a kernel bug or hardware bug. When running in a virtual machine,  this might instead indicate high levels of over-commitment (especially memory over-commitment) or other virtualization overheads. 

 Solution & Troubleshooting :

 Tried following things.
 1. Updated the Kernel to 3.10.0-327.18.2.el7.x86_64.
 yum update
 2. Increase the VM resources.
 3. installed open-vm-tools.
 yum install open-vm-tools

 4. But nothing worked. Finally i've find out that there are reservations set a resource pool.
 5. So , In my case it is VM ballooning for Memory over-commit. On My ESX server Pool Reservation is low. I've Increased it. That has solved the issue.
