VMware ESXi 6.0 Update 2 is out

VMware released ESXi 6.0 Update 2 on March 15th 2016. This release has a couple important bug fixes for ESXi hosts.

• Hostd stops responding when esxcli commands are executed using PowerCLI
  

• ESXi host experiences a purple diagnostic screen with multiple Correctable Machine Check Interrupt (CMCI) messages
  • The purple screen will show something similar to:
    PCPU : no heartbeat (2/2 IPIs received)

    0xXXXXXXXXXXXX:[0xXXXXXXXXXXXX]MCEHandleCMCI@vmkernel#nover+0xb4

• ESXi host with Netflow function enabled in VXLAN environment might fail with a purple diagnostic screen
  • The purple screen will show something similar to:
    @BlueScreen: PANIC bora/vmkernel/main/dlmalloc.c:4923 - Usage error in dlmalloc
    PTEs:0xnnnnnnnn;0xnnnnnnnn;0x0;
    0xnnnnnnnn:[0xnnnnnnnn]PanicvPanicInt@vmkernel#nover+0x37e
    ....
    ....
    0xnnnnnnnn:[0xnnnnnnnn]Net_AcceptRxList@vmkernel#nover+0x115
    

• Hostd logs flooded with error message multiple times in quick succession
  • The following VSI messages have been resolved:
    Failed to get vsi stat set: Sysinfo error on operation returned status : Not found. Please see the VMkernel log for detailed error information.
    

• Hostd randomly stops responding on hosts with 3D acceleration
  hostd.log might show something similar to:
  Crash Report build=2809209
  Signal 11 received, si_code 1, si_errno 0
  Bad access at 34
  eip 0xnnnnnnn esp 0xnnnnnnnn ebp 0xnnnnnnnn
