VCS CRITICAL V-16-1-51135 GlobalCounter not updated
Veritas Cluster Server (VCS) reports this error message in the engine log. It is a self-check message to determine if there are any delays due to a Global Atomic Broadcast (GAB) broadcast. You may also see this message if the high availability daemon (HAD) is busy and cannot update the GlobalCounter in the specified time.
Please check the following :
1. Load on the system i.e. memory, CPU, Disk space etc.
2. Network issues and connectivity, Check the network for delays and packet drop, which may affect GAB broadcast.
3. If still issue persists then reboot nodes.
