Full history node: Field '5/25' found in disallowed location

[imateapot]

Hi there!

I have a full history (almost fully synced) ripple node, or rather I had.
After planned node restart node just stops syncing. 
Node just spam the following messages into the log

Can please someone explain what "Field '5/25' found in disallowed location" means (cannot find anything in google)?
Does it mean that my node is broken and I have to resync a lot of terabytes?
