Issue

  • The ESXi host suddenly goes into a hung state.
  • There are no obvious HW failures from the IPMI event log and a PSOD(Purple Screen of Death) has not occurred.
  • Multiple vob.net.uplink.watchdog.timeout messages are created for vmnic0 and vmnic1.

Example:
2020-12-22T04:31:55.072Z: [netCorrelator] 336485006517us: [vob.net.uplink.watchdog.timeout] Watchdog timeout occurred for uplink vmnic1
2020-12-22T04:31:55.072Z: [netCorrelator] 336485006527us: [vob.net.uplink.watchdog.timeout] Watchdog timeout occurred for uplink vmnic0

2020-12-22T04:46:45.073Z: [netCorrelator] 337375006703us: [vob.net.uplink.watchdog.timeout] Watchdog timeout occurred for uplink vmnic0
