We too are running into this issue at multiple sites. Cloudberry support said its a known issue but that thought makes me cringe that this could crash our servers. My colleague can comment more on this issue and maybe provide a fix.

Hi Kirk, thanks. We too are plagued by this issue still. Deleting all vm backups would be difficult. Not sure if they are planning on a fix for this anytime soon....

I see...thank you for the reply.
