msg.vmxaiomgr.retrycontabort.rudeunplug:Operation on file

Hi Folks

I have a guest operating server that keeps getting the error "msg.vmxaiomgr.retrycontabort.rudeunplug:Operation on file"

If I abort and restart it comes up but can then for no reason get the error again and I have to abort

Any pointers on this would be great

Thanks
