I have been looking for information these days, but I haven't found a solution yet. So I came to the community to ask for help. Can you help me?

Thanks !

  - Probably a bug similar to : https://bst.cisco.com/bugsearch/bug/CSCwc80086?rfs=qvred
                         or               : https://bst.cisco.com/bugsearch/bug/CSCvw76327?rfs=qvred

   I would advise to upgrade to the latest advisory software version for the nexus,

Thanks, I also thought about whether I could fix this by upgrading the version. But at the moment we can't interrupt the business, so we want to see if there are other solutions. What reassured me was that only one system card would restart each time there was a failure. We have two. I still have time to make a choice.

 - @Dany970   Behavior of bugs is  difficult to predict and there could be various reasons why it it only seen on that module.
                        I don't think you will have other solutions besides upgrading as I suggested,  perhaps in the
                        near future when business permits you can have a scheduled downtime period ,
