This seems like you might have some template corruption. Before I run LD01, I would stat the DLC with LD32 to see what it shows. Is the 2nd TN in svc? You could try OUTing the TN or copy or move the good one somewhere else or printing the set config with LD20, and then OUTing both. Then putting it back as NEW. But I think you should do the template audit per NTPs. You mentioned the system is OP11C, I have heard there are some SCC cards that have flaky daughter boards that start loosing memory or other strange things occurring and the switch eventually crashing. So that is something to be aware of.
Hope this helps!
