    คำถาม

  • I have a cluster, 2 nodes. There are repeating events id 25, every few second:

    The MAC address 00-15-5D-AE-25-19 has moved from port 53A6AB28-EBD3-4F72-B690-69406077B8A7 (Friendly Name: vSwitchFN_External) to port 6D5ABBEF-0A8E-4F5D-8CC2-0871846CEF82 (Friendly Name: BCK).

    The events intensively fill the log and sometimes network connectivity for these virtual adapters (BCK, HB) is temporary lost.

    What is problem?
