Buenas, cuando hago housekeeping en el PT3 me da el siguiente error

There were errors during the housekeeping process:
Unable to execute query: VACUUM FULL;; Reason: Fatal Error (ERROR: could not read block 45216 of relation 1663/16403/263452: Invalid argument )
Unable to execute query: ANALYZE;; Reason: Fatal Error (ERROR: could not read block 45265 of relation 1663/16403/263452: Invalid argument )

El PT3 me funciona correctamente, es una version registrada para microlimites.

Alguien sabe a k se puede deber??

Gracias
