    PSOD: PCPU Locked up failed to ack tlb invalidate

    max70 Novice


      Hi everybody,



      I have a production esxi server (3i, 3.5.0,110271) on a ibm eServer x3400 with 10 virtual machines on it. The server stopped with a PSOD with a message saying:



      "PCPU 3 locked up failed to ack tlb invalidate" Panic from another cpu world 2955, machine check exception



      This happened twice in the last 2 weeks (!!). After rebooting the server the virtual machines started with no problems, i have no evidence of hardware problems in server hardware logs.



      Thanks in advance
