I noticed the following message in one of my VM’s vmware.log:
2016-01-17T06:58:41.066Z| vcpu-2| I120: GuestRpc: Channel 2, conflict: guest application toolbox tried to register, but it is still registered on channel 0 2016-01-17T06:58:41.066Z| vcpu-2| I120: GuestRpc: Channel 2 reinitialized. 2016-01-17T06:58:41.066Z| vcpu-2| I120: GuestRpc: Channel 2 reinitialized. 2016-01-17T06:58:41.066Z| vcpu-2| I120: GuestRpc: Channel 2 reinitialized.
A quick search on Goolge revealed VMware KB 2078823:
To work around this issue, disable general virtual machine logging to the vmware.log file for the virtual machine:
- Click the virtual machine in the Inventory.
- In the Summary tab for that virtual machine, click Edit Settings.
- In the virtual machine Properties, click the Options tab.
- Under Advanced, click General and deselect Enable logging.
- Click OK to save the change.
The above didn’t work for me and I actually had to uninstall the VMware Tools and install the most current version.
By the way, I’m also still running ESXi 5.1 on host in my lab, I’ll probably get it upgraded soon, since this issue has already been fixed in some versions of ESXi 5.1, 5.5 and 6.0
