Unfortunately, your Ontap (7-mode) version is way out-of-date and for such errors (panic) it is suggested to contact support and upload the core file. However, I don't think that is an option available in your case. There could be multiple causes, only after analyzing the core-dump file that the engineering/support could advise what might have caused it.  Recommendation will be to upgrade the OS, i.e data ontap from 8.1 to 8.2 (last upgradable version).
