PostgreSQL crashes on Windows 2003

Hi,

The PostgreSQL of a customer database (running on Windows 2003) crashed
and wrote the messages below in the logfile. According to the customer
the drives are working OK, partitions are not full and nothing has
changed in the permissions. The customer could restart the PostgreSQL
service manually, without resorting to a backup.

Could this be the result of not enough check_point segments?
