prealloc: broken table, ram-attributes length overflow

I have a manticore database, and after a power outage, one of the real time index is not available:

This is what I can see in the manticore logs:

WARNING: table 't1': prealloc: broken table, ram-attributes length overflow (len=357621912, max=112012023) - NOT SERVING

How can I fix it?

Seems you table is broken. You need restore backup or reindex your data from scratch.
