                                      Environment

                                      VMware vSphere ESXi 6.0

                                      Cause

                                      This issue occurs because devfs heap is full.

                                      Resolution

                                      This is a known issue affecting ESXi 6.0.

                                      Currently, there is no resolution.

                                      To work around this issue, increase the value of storageMaxDevices to 1024.

                                      To increase the value using vSphere Client, go to Software > Advanced settings > VMKernel > vmkernel.boot.StorageMaxDevices.
