VCF Operations for Logs 9.0.x
This behavior occurs in VCF Ops 9.0.x deployments after VC/ESX log collection has been configured through the VCF Operations -> Log Management -> Log Collection UI.
When log collection is established in this way, VCF Operations for Logs makes repeated calls to VC and ESX to maintain the log collection configuration. The primary node restarts are due to the incorrect closing of TLS connections, which eventually causes OutOfMemory errors.
When the OutOfMemory error occurs, the primary node will restart and will recover. An email notification may be received. During the restart the UI will not be available. After the restart completes, the system will operate as normal.
Broadcom is aware of this issue in VCF Operations for Logs 9.0.x and is currently developing a permanent fix. Subscribe to this article to receive notifications as updates become available.
