osm2pgsql problem

Ich frage mal hier, weil da doch einige mit Fachwissen präsent sind. Habe gestern versucht, einen Planet-Extrakt in eine Postgres/Postgis zu importieren, und gegen Ende gab es einen Fehler. Hier die Ausgabe:

Das Problem scheint hier zu liegen: "SQL command failed: ERROR: could not seek to block 4742566397934611732 of temporary file". Ist das ein Festplattenfehler? Die Blocknummer ist ja viel zu hoch. Oder könnte das auch von osm2pgsql kommen?
