Aurora is different from PostgreSQL.  In particular, the query cancellation
error you are showing does not occur in the PostgreSQL code base.  So unless
somebody who knows Aurora internals happens to read your question, you won't
get a good answer.

You could check if your I/O quota are exceeded...
