Re: URGENT: Unable to schedule async job for command com.cloud.vm.VmWorkStart, unexpected exception


Hi

I think you hit https://github.com/apache/cloudstack/issues/2880

Is this already 4.11.2?

We have also seen this in our lab, could not really reproduce it, seems
to be a race condition.

Regards
René
