Hi Robert,
Sorry for the late reply, I was not here last week.
About your question: "That's kind of surprising, but I can't help wondering if it's a bug in what virtualization tool you are using."I noticed the problem FIRST on VM.  And by pausing/stopping/launching a VM it was easy to get these error back.
But since some weeks, I also had duplicates on real server.  And same result if I try to launch a VACUUM: crash with the same assertion.Which "stack trace on the assertion failure" do you want to have ?
Regards,



Pascal BORSCHNECK
