Conditions
This issue has been reported only on N7K.
Workaround
There is no workaround, upgrade is necessary to clear the errors.
Further Problem Description
In some events, the device will save the core files and can be seeing in the "show core" output. The file is necessary to confirm the issue.
In some cases the cores are corrupted or the backtrace is empty.
Confirm that the logflash is properly inserted. If not it might cause the cores to not be saved.
