Perhaps WAL is accumulating from those table rewrites. Could be your WAL settings, and that the WAL will get reused eventually, which is no problem. Could be you have WAL archiving or replication slots, and archiving or replication is broken, and WAL will accumulate until it fills the disk.

That needs to be looked at. But the question still remains as to why you are running VACUUM FULL?
