DNA server CrashLoopBackOff error

Mostafa Alzareef — Thu, 25 Dec 2025 11:55:12 GMT

I have 3 DNAC server nodes. I finalized the conf for the 3 and created the H, A, but after I turn off the devices and turn them on, the attached log error message appears for me using maglev most of them (CrashLoopBackOff)

ndp pipelineruntime-taskmgr-assurance-2-7ccd9fdb7c-rkf56 0/1 CrashLoopBackOff 5 4m58s 169.254.40.152 X.X.X.35 <none> <none>

is the NTP and DNS MTU all ok, then Try - maglev service stop all followed by maglev service start all

check the logs

kubectl get pods -n assurance | grep CrashLoopBackOff

Hi,

You most probably hit this one: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwm60177

You have both a WA and a solution presented.

Thanks,

Cristian.

Thanks, all, I kept DNA continuing to work for one day, and returned, I found the issue solved, and I can access the DNA now

Hi,

Strongly suggest to take a look at my previous answer; there are no miracles / magic wands in technology, and leaving the situation as is, self-fixed, will most probably kick back in near future.

Thanks,

Cristian.

DNAC takes a long time to deploy, depending on the compute.
