Something is seriously wrong with your cluster. AHM epoch should always be less than LGE epoch , but does not seem so in your case. You may want to add details like version, configuration and how did you discover this and the contents from select * from system;

Looks like a bug to me...

It's on a dev cluster, so I just blatted it and re-created it. Not quite sure what led to it, but it's back to normal now, so I'll just keep my eyes open to see if it happens again. Thanks for the response. Neil

Hi,

I do not think there is a straight forward solution for this. May be few projections causing this issue.
Incase you face this further, you can open a CASE with HP Vertica technical support.

Thanks,
