PLATFORM-1-PFM_ALERT: Module 30 has experienced a kernel panic.

Hi community,

On one of the Nexus 9k's with version 7.0(3)I7(5a) that I manage, logs have appeared in the system controller. Could you help me where to send the reviews?

yes i would advise to upgrade and test it. some time we do see re-appear bugs on other version too.

if you like to pursue (suggest to have a TAC call will help you).

Thanks for your answer Balaji,

I have some additional queries:
- The N9K has version 7.0(3)I7(5a) and in the affected releases it is not listed, does the bug also apply to version 7.0(3)I7(5a)?
- Do you consider it necessary to upgrade? If so, which one would you recommend?
