DNAC unreachable GUI/ICMP/CLI/KVM

[Tinz]

I found an issue DNAC unreachable GUI/ICMP/CLI/KVM 2 time in 1 week.

DNAC single node running on version 2.3.3.6-70045 

Workaround: Reload Host from CIMC

I guess the issue is memory leaks because memory is over 80% in a few days.

Cisco TAC can't find out the root cause.

Please advise what should i do.

Thanks.

Hey Tinz,

Do you see any alerts or warnings from the CIMC UI that may indicate a potential HW issue?

Have you provided Cisco TAC with a RCA bundle from DNA Center along with a CIMC support bundle for root cause?

Hey Dan

Thank you for answer. as checked on CIMC is normal confirmed by Cisco TAC.

I've provide RCA and CIMC after the reloaded server and Cisco TAC can't find out the root cause ,because they need RCA during issue happen but we can't collect at all.
