  • ESXi hosts might fail with a purple screen and display error messages similar to the following when you perform vMotion:

    @BlueScreen: #PF Exception 14 in world 249122:vmotionStrea IP 0xnnnnnnnnnnnn addr 0xnnnnnnnnnnnn
    2014-07-16T07:09:57.026Z cpu62:249122)Code start: 0xnnnnnnnnnnnn VMK uptime: 0:19:41:16.346
    0xnnnnnnnnnnnn:[0xnnnnnnnnnnnn]NUMALatency_GetNodeHops@vmkernel#nover+0x22 stack: 0xnnnnnnnnnnnn

  • Under certain conditions, a userworld program might not function as expected and might lead to accumulation of large number of zombie processes in the system. As a result, the globalCartel heap might exhaust causing operations like vMotion and SSH to fail as new processes cannot be forked when an ESXi host is in the heap memory exhaustion state. The ESXi host might not exit this state until you reboot the ESXi host.
    Warning messages similar to the following might be written in the vmkernel.log file:

    2014-07-31T23:58:01.400Z cpu16:3256397)WARNING: Heap: 2677: Heap globalCartel-1 already at its maximum size. Cannot expand.

  • ESXi 5.5.x host might fail with a purple screen with error messages similar to the following:
