DCX switch CPU running at 100% all time


I recently noticed, our 2 DCX switches (1 in fab A & another in fab B), both are running CPU usage at 100% since long time.. All other switches are running okay in fabric. What is causing high CPU usage on these 2 switches ? Is there any problem in future if we do not solve it ? How we can solve it ? We are running version 6.4.2 on both DCX.

Re: DCX switch CPU running at 100% all time

1. You can try diagnosing your issue with "top" command. You might need to be root for that.
2. As a one off remedy you might try doing "hafailover".
3. As a long term solution you most likely need to review and update your Fabric OS.
