Resolved Issues
-
Fixed Issue 2989776: VMkernel logs filled up by, “Cannot add Arp VMI, reached max limit of 1.”
Due to duplicate MAC issue, VMware ESXi log file (/var/log/vmkernel.log) is rapidly filled up by excessive messages indicating max ARP limit had been reached. Resolution: NSX for vSphere 6.4.14 has reduced the default log level for this message from Error to Debug.
-
Fixed Issue 3003814: NSX Manager unresponsive until reboot.
Unavailability of NSX Manager.
-
Fixed Issue 3020991: Multiple ESX hosts PSOD with large number of pending ARP entries across DRs.
When workloads generate larger number of TCP/UDP traffic for non-existent IPs (typically by a scanner tool), DRs initiate ARPs to those IPs. DRs couldn't complete processing these large ARPs resulting in ESX watchdog process to PSOD the host.
