2、the "uname -a " information is:
Linux linux 4.4.103-92.56-default #1 SMP Wed Dec 27 16:24:31 UTC 2017 (2fd2155) 
x86_64 x86_64 x86_64 GNU/Linux

- is this in dom0 or in a domU (if domU: HVM or PV)?
        In Dom0, our domU run windows7 OS. 

- from the messages in guess the system is hanging, not crashed?
        the whole server is hanging and can not be connected or operate anyway.
- what are the other vcpus of the domain doing (how to get this info
  is depending on the dom0/domU question above)?
        the whole server is hanging and can not be connected. 


Best regards

This is a Linux problem. You need to supply more information:

- which kernel version?
- is this in dom0 or in a domU (if domU: HVM or PV)?
- from the messages in guess the system is hanging, not crashed?
- what are the other vcpus of the domain doing (how to get this info
  is depending on the dom0/domU question above)?
