Issue/Introduction

• Virtual Machine console crashes at randomly on Cloud Director 10.2.x and10.3.x versions.
• Restarting the cell allows the console to work for a short period of time.

Environment

VMware Cloud Director 10.2.x and 10.3.x versions

Resolution

Resolved in VMware Cloud Director 10.4.

Workaround:

1. Open an SSH session to each cell.
2. Set the workaround: /opt/vmware/vcloud-director/bin/cell-management-tool manage-config -n consoleproxy.cores.max -v "0"
3. List the new default: /opt/vmware/vcloud-director/bin/cell-management-tool manage-config -n consoleproxy.cores.max -l
4. Restart the cell one at a time to implement the changes: systemctl restart vmware-vcd

Please note if you are only running one cell, this will involve downtime.
