@Shiro I added store logging, nothing yet.
@normis I can't make a supout, because it appears read-only. sup-output hits 100%, but doesn't show a file created. Also, if I try to create a backup it says "Couldn't make backup - action failed (6)". Bad blocks information isn't present for Cloud Cores under the resources menu (nor is other sector information like is available on other models).
Also new, this is affecting a router running 6.11 as well, not just newer versions as earlier expected.
I agree this is a huge issue.
@janisk netinstall will require changing out the unit as we don't have that as an option at those sites. Are you sure this will fix the issue? Is this a hardware or software problem or unknown?
