Esxi host reboot when virtual machine started

In Virtual machines with disk size larger than 256GB in VMFS5 and larger than 2.5TB in VMFS6, you see below symptoms

  • .Host becomes unresponsive, cannot restart specific hung virtual machines.
  • Host requires a reboot to restart the virtual machines.
  • In the /var/log/vmkernel.log file, you see entries similar to:….. cpu46:712802)WARNING: VSCSI: 3488: handle 19192(vscsi0:1):WaitForCIF: Issuing reset; number of CIF:1

Virtual machine IO requires accessing VMFS metadata associated with the virtual disks. Write IO may require updating of this metadata due to allocation of new data blocks.
There is a synchronization issue while accessing this file block metadata from multiple threads causing a deadlock between threads.
