firtst node:CentOS:7.6,Kernel:5.4.31
second node:CentOS:7.6,Kernel:3.10.0-957
when i enable memory hotplug ,VM is run normal allocate less than 48G Ram,but when i allocate more than 48G Ram,and reboot the Guest,it's unnormal:
firtst node display “system deadlock on memory” in console;
second node report “echo 0 /proc/sys/kernel/hung_task_timeout_secs” in console
 
Can you provide the syslog from that time? Please also upgrade to the latest PVE 5 version or even to PVE 6. (PVE 5 will be EOL in July 2020)
And provide the complete task log from the VM start.
