The journal stores a lot of metadata for each log entry, so the
"alllogs" size is not a good indicator of disk space requirements.
Use "journalctl -o verbose" to see all information that is actually
stored.

So basically I believe this is (at least mostly) a case of the
configured space not being enough to store more logs, given all the
metadata space requirements.
